	abstract = {The reaction of the dinuclear [RuCl2(dppb)](2)(mu-dppb) (dppb = 1,4-bis(diphenylphosphino)butane) with Cl-2 in MeOH for similar to 30 min at room temperature gives the bright-red solid mer-RuCl3(dppb)(H2O) (1); Cl-2 treatment for similar to 10 min affords the red-brown, mixed valence complex [RuCl(dppb)](2)(mu-Cl)(3) (2). Controlled bulk coulometric reduction of 50\% of the content of a CH2Cl2 solution of 1 also produces 2, formed by the reaction of 1 with "RuCl2(dppb)" produced in situ during the electrolysis. Complexes 1 and 2 were characterized by spectroscopic techniques [including electron spin resonance (ESR)], magnetic moments and cyclic voltammetry, and the structure of 1 was determined by X-ray diffraction. The structure shows that the aquo ligand forms hydrogen bonds with two cis-chlorine ligands of the neighboring molecule of the complex; this interaction gives rise to exchange coupling between two Ru(III) centers that is reflected in the ESR spectrum. A species 3 analogous to 1 has been obtained with the diop ligand [diop = (2R,3R)- or (2S,3S)-O-isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane] , on using RuCl2(diop)(PPh3) or [RuCl(diop)](2)(mu-Cl)(3) as precursors. The RuCl3(P-P)L complexes (P-P = dppb, diop; L = dimethyl sulfoxide, MeOH) are readily synthesized from 1 or 3.},

	abstract = {Kinetic studies on the H-2-hydrogenation of styrene catalyzed by [RuCl(dppb)(mu-Cl)](2) (dppb = Ph(2)P(CH2)(4)PPh(2)) in N,N-dimethylacetamide solution, near ambient conditions have revealed a first-order dependence on Ru, and dependences on H-2 and on styrene that are first-order at lower concentrations and decrease with increasing concentration. Considered along with NMR and tensiometric data, the findings are interpreted in terms of a basic hydride route in which an initially formed, dinuclear, molecular hydrogen complex (eta(2)-H-2)Ru(dppb)(mu-Cl)(3)RuCl(dppb) transfers both hydrogens to the styrene.},

The [RuCl(binap)]2(mu-Cl)2 species is also formed in solution by dissociation of PPh3 from RuCl2(binap)(PPh3) which is synthesized by phosphine exchange with RuCl2(PPh3)3. From the [RuCl(P-P)]2(mu-Cl)2 complex (P-P = Ph2P(CH2)4PPh2), a range of L(P-P)Ru(mu-Cl)3RuCl(P-P) species is readily formed, where L includes an amine, acetone, NN-dimethylacetamide, Mel, PhCN, CO, N2 or H2; the L = NEt3 adduct is made also from RUCl2(dppb)(PPh3), while the corresponding dimethyl sulfoxide adduct (L = DMSO), 17e, is synthesized directly from cis-RuCl2(DMSO)4 and the phosphine. P-31{H-1} NMR data are presented for the Ru(II) species, while characterization of 17e includes an X-ray_crystallographic analysis that confirms the trichloro-bridged formulation. Crystal data are as follows: triclinic, P1BAR},
