Abstract：
:Series of dinuclear species [Ru(2)(L)(2)(LH)(2)-mu-S(2)Cl(2)], [Ru(2)(L)(2)(LH)(4)-mu-Se(2)Cl(2)] (L=L(1)H and L(3)H) and [Ru(2)(L(2))(2)(L(2)H)-mu-Se(2)Cl(2)].2H(2)O, where L(1)H, L(2)H and L(3)H represent for 2-mercapto-5-phenyl-1,3,4-oxadiazole, 2-mercapto-benzimidazole and 2-mercapto-benzothiazole, respectively, have been prepared and characterized by their elemental analyses and spectral (IR, UV-visible, 1H NMR and FAB mass) data. The diamagnetism of these complexes are indicative of an exchange coupled dinuclear ruthenium(III) species containing S(2)(2-) and Se(2)(2-) bridges. The complexes along with free heterocycles (L(1)H-L(3)H) as well as RuCl(3) x 3H(2)0 were tested for their nitrate and nitrite reductase activities. The electrochemical behaviour of the complexes showed irreversible oxidation peaks at +(1.04-1.40) V quite comparable to those reported for sulphido bridged complexes.
