Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).
Complexes of the potentially bidentate ligand 2,2?-biphenol (H2biph) have been prepared and studied by electrochemical and UV/Vis/NIR spectroelectrochemical methods. The complexes studied are [(Tp*)M(O)(biph)] [M = Mo, W; Tp* = hydrotris(3,5-dimethylpyrazolyl)borate], [W(biph)3], [Cl6W2(biph)3] and [Ru(bpy)2(biph)], and all have been structurally characterised. [(Tp*)M(O)(biph)] (M = Mo, W) both undergo reversible M(IV)/M(V) couples at negative potentials, with the redox potential for the W(IV)/W(V) couple being 580 mV more negative than that of the Mo(IV)/Mo(V) couple; the redox potentials are similar to those which occur in the complexes [(Tp*)M(O)(OC6H5)2] with two monodentate phenolate ligands. The structure of [W(biph)3] is essentially octahedral but with a distortion towards trigonal prismatic; the complex undergoes two metal-centred redox processes, W(IV)/W(V) and W(V)/W(VI) which were characterised spectroelectrochemically. An unexpected new W(VI) complex [Cl6W2(biph)3] has the structure [{WCl3(biph)}2(mu-biph)], in which each W(VI) centre has a terminal chelating biphenolate ligand, and other highly twisted biphenolate ligand acts as a bis-monodentate bridge spanning the two W(VI) centres. [Cl6W2(biph)3] undergoes two successive W(V)/W(VI) redox processes at negative potentials, with a separation of 170 mV indicating a through-space Coulombic interaction between the metal centres; spectroelectrochemistry showed no evidence of an inter-valence charge-transfer band in the mixed-valence W(V)-W(VI) state. [Ru(bpy)2(biph)] has a Ru(II)/Ru(III) couple at a potential very similar to related ruthenium complexes with a (pyridine)4(phenolate)2 donor set.
