The effect of protonation on the spectroscopic properties of Re(I) and Ru(II) complexes with the ligand 11-triphenylamine-dipyrido[3,2-a:2?,3?-c]phenazine (dppz-TAA) are investigated. For [Re(CO)3Cl (dppz-TAA)] protonation with triflic acid in CH2Cl2 results in a depletion of the intraligand charge-transfer transition at 500 nm (epsilon = 17700 M-1 cm-1) and the concomitant grow-in of a band at 780 nm (epsilon = 18200 L mol-1 cm-1). Resonance Raman spectra of the protonated species show a strong band at 1628 cm-1 attributed, through DFT modeling, to a TAA mode with bending of the phenazine NH linkage. The low energy band is also predicted by TD DFT. The behavior of [Ru(bpy)2(dppz-TAA)]Cl2 was studied in aqueous solution as a function of pH. The electronic absorption spectrum shows modest changes as a function of pH. The excited state properties show a short-lived emissive state (lambdamax = 500 nm) that is diminished in intensity at lower pH. The compound also has a long-lived dark state with absorption features at 420 and 700 nm; the lifetime of this state is also pH sensitive varying from 2500 to 500 ns. The dark long-lived state is probed with transient resonance Raman spectroscopy and is assigned as a 3pi; pi? ligand state. This is consistent with DFT studies. From these data the pKa for [Ru(bpy)2(dppz-TAA)]Cl2 is estimated as 4.5.

The EPR spectra of CsMgCl3 crystals doped with Gd(III) and Ru(III) contain the resonances from a magnetically coupled Gd(III)-Ru(III) pair.The pair spectrum exhibits the fine structure characteristic of a Gd(III) ion (S=7/2) in an axial lattice site.At 77 K the weak coupling with the Ru(III) ion (S=1/2) splits each resonance into a doublet.The spectrum is well enough resolved to allow a characterization as a function of crystal orientation.A spin Hamiltonian which assumes a simple anisotropic interaction between the two ions is adequate to describe the spectrum (Etap=JzSzSz’+Jxy(SySx’+SySy’); where =+0.0055 cm-1 and =0.020 cm-1).The analysis determines that the principal g values of Gd(III) and Ru(III) have opposite sign (for Gd(III): gz=+1.991 and =1.991; for Ru(III): gz’=-2.35 and =1.62).The magnetic properties of the Gd(III)-Ru(III) dimer are discussed.As a part of this analysis, the spectra of a number of monomeric centers containing Gd(III) and Ru(III) were characterized.The properties of these centers are also discussed.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 20759-14-2, Name is Ruthenium(III) chloride hydrate, Recommanded Product: 20759-14-2.

Some metal complexes of N,N-dihexyl-N?-benzoylthiourea (DHBT) of the type M(DHBT)n [ M=Ni, Pd, Pt, (n=2), Ru, (n=3)] have been synthesised and studied using DTA and TG. These complexes undergo only the pyrolytic decomposition process. The orders, n, the activation energies, E, the pre-exponential factor, A, and the entropies, DeltaS of the thermal decomposition reactions have been derived from thermogravimetric (TG) and differential thermogravimetric (DTG) curves. The characterisation of the end products of the decomposition was achieved by X-ray diffraction. UV-Vis and IR spectra were used for the investigation of characteristic absorption bands and the structural characterisation of ligand and the metals, respectively. Using the Coats and Redfern and Horowitz and Metzger methods performed kinetic analysis of the thermogravimetric data.
