Abstract: Reactions of [{Ru(η33-C10H16)(μ-Cl)Cl}2] with 1,4-dicyanobenzene (DCB) or 1,4-piperazinedicarbonitrile (PPz) in dichloromethane in 1:2 and 1:1 molar ratio gives mononuclear complex [{Ru(η33-C10H16)Cl2(L)] and binuclear complex [{Ru(η33-C10H16)Cl2}2(μ-L)]. However, its reaction with 1,4-dicyanotrans-2-butene (DCBT) gives only a binuclear complex [{Ru(η33-C10H16)Cl2}2(μ-DCBT)] and with 1-piperidinecarbonitrile (PPd), a mononuclear complex [{Ru(η33-C10H16)Cl2(L)]. The mononuclear complexes resulting from the reaction of [{Ru(η33-C10H16)(μ-Cl)Cl}2] with DCB or PPz possesses pendant nitrile group. Nucleophilicity of the pendant nitrile group in these complexes have been employed in the synthesis of binuclear mixed valence-bridged complexes, in which, the respective metal centers are bridged by DCB or PPz ligand. The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H NMR and 13C NMR spectra).
