Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate, is researched, Molecular C8H12BCuF4N4, CAS is 15418-29-8, about [Cu15(PPh3)6(PET)13]2+: a Copper Nanocluster with Crystallization Enhanced Photoluminescence.Name: Copper(I) tetra(acetonitrile) tetrafluoroborate.

Due to their atomically precise structure, photoluminescent copper nanoclusters (Cu NCs) have emerged as promising materials in both fundamental studies and technol. applications, such as bio-imaging, cell labeling, phototherapy, and photo-activated catalysis. In this work, a facile strategy is reported for the synthesis of a novel Cu NCs coprotected by thiolate and phosphine ligands, formulated as [Cu15(PPh3)6(PET)13]2+, which exhibits bright emission in the near-IR (NIR) region (≈720 nm) and crystallization-induced emission enhancement (CIEE) phenomenon. Single crystal x-ray crystallog. shows that the NC possesses an extraordinary distorted trigonal antiprismatic Cu6 core and a, unique among metal clusters, “”tri-blade fan””-like structure. An in-depth structural investigation of the ligand shell combined with d. functional theory calculations reveal that the extended C-H···π and π-π intermol. ligand interactions significantly restrict the intramol. rotations and vibrations and, thus, are a major reason for the CIEE phenomena. This study provides a strategy for the controllable synthesis of structurally defined Cu NCs with NIR luminescence, which enables essential insights into the origins of their optical properties.

Acetelyenediide (C22-) species have been encapsulated in bimetallic and trimetallic clusters: [(AuL)6Ag7(CC)3](BF4)7 (2) and [(AuL)6AgCu6(CC)3](BF4)7 (3), L = phenylbis(2-pyridyl)phosphine (PPhpy2). Single-crystal X-ray diffraction anal. revealed that they are isostructural and six silver atoms in 2 are replaced with copper in 3. Both clusters have a trefoil skeleton, which can be viewed as three trigonal bipyramidal (LAu-CC-AuL)M2Ag (M = Ag/Cu) motifs sharing a common silver atom. TDDFT calculations showed Cu-doping significantly increases the energy level of (C2-Cu)-involved occupied orbital, thus inducing interesting transition coupling of dual-emission at low temperature This work not only provides a strategy for constructing heterometallic clusters, but also shows the prospect for pursuing novel thermochromic luminescent materials by incorporating multi-congeneric metal components.

Synthetic Route of C8H12BCuF4N4. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate, is researched, Molecular C8H12BCuF4N4, CAS is 15418-29-8, about Synthesis of an N, N-diethyl-tert-butylazothioformamide ligand and coordination studies with Copper(I) salts.

Redox-active azothioformamides ligands rapidly coordinate to transition metals and are excellent substrates for monitoring host-guest binding interaction mechanisms as they can exhibit unique coordination complexes while producing an increase in extinction coefficient upon addition of metal salt. Herein, an alkyl derivative, N,N-diethyl-t-butylazothioformamide, was synthesized and fully characterized, including x-ray crystallog. Crystalline coordination complexes were prepared with various copper(I) salts (CuBr, CuI and [(MeCN)4Cu]BF4) producing both 1:1μ-X dimers from copper(I) halides and a distorted tetrahedral 2:1 species with non-coordinative tetrafluoroborate salt. Bond distances and angles suggest neutrally bound alkyl azothioformamide ligands with copper(I), indicating no redox activity upon binding. UV-visible titration studies with copper(I) salts and subsequent data evaluation with both 1:1 and 2:1 non-linear regression binding models suggest inconsistent mechanisms with copper(I) salts.

From this literature《Synthesis of an N, N-diethyl-tert-butylazothioformamide ligand and coordination studies with Copper(I) salts》,we know some information about this compound(15418-29-8)Synthetic Route of C8H12BCuF4N4, but this is not all information, there are many literatures related to this compound(15418-29-8).

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate(SMILESS: [Cu+](N#CC)(N#CC)(N#CC)N#CC.[B+3]([F-])([F-])([F-])[F-],cas:15418-29-8) is researched.Quality Control of 5-Iodo-2-furaldehyde. The article 《Comparative Study of the Supercapacitive Performance of Three Ferrocene-Based Structures: Targeted Design of a Conductive Ferrocene-Functionalized Coordination Polymer as a Supercapacitor Electrode》 in relation to this compound, is published in Chemistry – A European Journal. Let’s take a look at the latest research on this compound (cas:15418-29-8).

As redox-active based supercapacitors are known as highly desirable next-generation supercapacitor electrodes, the targeted design of two ferrocene-functionalized (Fc(COOH)2) clusters based on coinage metals, [(PPh3)2AgO2CFcCO2Ag(PPh3)2]2·7 CH3OH (SC1: super capacitor) and [(PPh3)3CuO2CFcCO2Cu(PPh3)3]·3 CH3OH (SC2), is reported. Both structures are fully characterized by various techniques. The structures are utilized as energy storage electrode materials, giving 130 F g-1 and 210 F g-1 specific capacitance at 1.5 A g-1 in Na2SO4 electrolyte, resp. The obtained results show that the presence of CuI instead of AgI improves the supercapacitive performance of the cluster. Further, to improve the conductivity, the PSC2 ([(PPh3)2CuO2CFcCO2]∞), a polymeric structure of SC2, was synthesized and used as an energy storage electrode. PSC2 displays high conductivity and gives 455 F g-1 capacitance at 3 A g-1. The PSC2 as a supercapacitor electrode presents a high power d. (2416 W kg-1), high energy d. (161 Wh kg-1), and long cycle life over 4000 cycles (93 %). These results could lead to the amplification of high-performance supercapacitors in new areas to develop real applications and stimulate the use of the targeted design of coordination polymers without hybridization or compositions with additive materials.

Yldiides have unique electronic properties and donor abilities, but as ligands in transition metal complexes they are scarcely represented in the literature. Here, the controlled synthesis of a series of polynuclear gold yldiide complexes derived from triphenyl(cyanomethyl)phosphonium bromide, [Ph3PCH2CN]Br, under mild conditions is described. Anionic dinuclear NBu4[(AuX)2{C(CN)PPh3}] (X = Cl, C6F5) or trinuclear derivatives NBu4[Au3X2{C(CN)PPh3}] bearing terminal chloride or pentafluorophenyl groups and bridging yldiide ligands have been prepared These compounds evolve in solution giving rise to the formation of an unprecedented tetrameric gold cluster, [Au4{C(CN)PPh3}4], by the loss of the gold complex NBu4[AuX2]. This gold cluster can also be prepared in high yield by a transmetalation reaction from the analogous tetrameric silver cluster, and two geometric isomers have been characterized, their formation dependent on the synthetic route. The triphenylphosphonium cyanomethyldiide ligand has also been used to build different dinuclear and trinuclear cationic complexes bearing phosphine or diphosphine ancillary ligands and bridging yldiide moieties. Further coordination through the cyano group of the yldiide ligand gives heterometallic trinuclear or pentanuclear derivatives Structural characterization of many of these compounds reveals the presence of complex mol. systems stabilized by gold···gold interactions and bridging yldiide ligands.

Author is Zheng, Dan; Huang, Ting-Hong; Luo, Cheng; Tang, Jing.

Three dinuclear Cu(I) complexes, [Cu2(pnd)(PPh3)4](BF4)2 (1), [Cu2(pnd)(dppp)2] (BF4)2 (2), and [Cu2(pnd)(DPEphos)2](BF4)2 (3) (PPh3 = triphenylphosphine, dppp = 1,3-bis (diphenylphosphino)propane, DPEphos = bis(2-diphenylphosphinophenyl)ether, pnd = N, N’-bis (pyridin-2-ylmethylene)naphthyl-1,5-diimine), were prepared and characterized by IR, 1H NMR, 31P NMR, 13C NMR, XRD, elemental anal. and x-ray crystal structure anal. The structural anal. reveals that the flexible pnd in 1-3 acts in a trans bridging coordination mode to connect two Cu+ ions, forming a S-shape conformation, while each of Cu(I) ion is four-coordinate N2P2, adopting a distorted-tetrahedral geometry. DFT calculations show that the HOMOs of complexes 1-3 are primarily located on the copper d-orbital and the phosphine ligand, together with a specific contribution of pnd, while LUMOs are mostly composed of pnd with admixed Cu(I) d-orbital character. Corresponding calculations of at. charges indicate that the charge of the copper atom in complexes 1-3 is below +1, while the total charges of the coordinated atoms are 0.743-0.786. Moreover, the solid-state emission spectra of complexes 1-3 show the existence of broad emission bands at 350-550 nm.
