  Reaction of 2,2′-dithiodipyridine (DTDP) with cis-Ru(bpy)2Cl2 (bpy = 2,2′-bipyridine) and cis-Ru(phen)2Cl2 (phen = 1,10-phenanthroline) respectively yields the dicationic species [Ru(bpy)2(DTDP)]2+ and [Ru(phen)2(DTDP)]2+ in which the S–S bond of DTDP remains intact. The S–S bond undergoes a reductive cleavage when DTDP is reacted with cis-Ru(bisox)2Cl2 (bisox = 4,4,4′,4′-tetramethyl-2,2′-bisoxazoline) under identical conditions to generate the monocationic species [Ru(bisox)2(2-thiolatopyridine)]+. The intramolecular electron transfer between the metal and the S–S bond is found to be subtly controlled by the crystal field strength of the ancillary bidentate N-donor ligands.

  2,2′-二硫代二吡啶 (DTDP) 分别与 cis-Ru(bpy)2Cl2 (bpy = 2,2′-联吡啶) 和 cis-Ru(phen)2Cl2 (phen = 1,10-菲咯啉) 反应生成双阳离子[Ru(bpy)2(DTDP)]2+ 和 [Ru(phen)2(DTDP)]2+ 物种，其中 DTDP 的 S-S 键保持完整。当 DTDP 与 cis-Ru(bisox)2Cl2 (bisox = 4,4,4′,4′-四甲基-2,2′-双恶唑啉)在相同条件下反应时，S-S 键发生还原断裂，生成单阳离子种类[Ru(bisox)2(2-硫代吡啶)]+。研究发现金属和 S-S 键之间的分子内电子转移受到辅助二齿 N 供体配体的晶体场强度的微妙控制。

  Starting from previously reported cis-Ru(MeL)(2)Cl-2, where MeL is 4,4,4',4'-tetramethyl-2,2'-bisoxazoline, cis-Ru(MeL)(2)Br-2 (1), cis-Ru( MeL)(2)I-2 (2), cis-Ru(MeL)(2)(NCS)(2) center dot H2O (3), cis-Ru(MeL)(2)(N-3)(2) (4) and cis-[Ru(MeL)(2)(MeCN)(2)](PF6)(2) center dot (CH3)(2)CO (5) are synthesised. The X-ray crystal structures of complexes 1, 2, 3 and 5 have been determined. All the five new complexes have been characterized by FTIR, ESIMS and H-1 NMR. In cyclic voltammetry in acetonitrile at a glassy carbon electrode, the complexes display a quasireversible Ru(II/III) couple in the range 0.32-1.71 V versus NHE. The Ru(II/III) potentials yield a satisfactorily linear correlation with Chatt's ligand constants P-L for the monodantate ligands. From the intercept and by comparing the known situation in Ru(2,2'-bipyridine)(2)L-2, it is concluded that MeL, a non-aromatic diimine, is significantly more pi-acidic than 2,2'-bipyridine.

• Acid dissociation of 2,2′-dipyridylamine in non-aqueous medium when chelated to some Ru(II)N4 cores

  [Ru(2,2'-bipyridine)(2)(Hdpa)](BF4)(2) center dot 2H(2)O (1), [Ru(1,10-phenanthroline)(2)(Hdpa)] (PF6)(2) center dot CH2Cl2 (2) and [Ru(4,4,4',4'-tetramethyl-2,2'- bisoxazoline)(2)(Hdpa)] (PF6)(2) (3) are synthesized where Hdpa is 2,2'-dipyridylamine. The X-ray crystal structures of 1 and 2 have been determined. Hdpa in 1 and 2 is found to bind the metal via the two pyridyl N ends. Comparing the NMR spectra in DMSO-d(6), it is concluded that 3 has a similar structure. The pK(a) values (for the dissociation of the NH proton in Hdpa) of free Hdpa and its complexes are determined in acetonitrile by exploiting molar conductance. These correlate linearly with the chemical shift of the NH proton in the respective entities. (C) 2007 Elsevier B.V. All rights reserved.
