    • Abstract

       

      Reactions of the cyanide complexes of the type [(Ind)Ru(PPh3)2CN] (1), [(Ind)Ru(dppe)CN] (2), [(Cp)Ru(PPh3)2CN] (3), with the corresponding chloro complexes [(Ind)Ru(PPh3)2Cl] (4), [(Ind)Ru(dppe)Cl] (5), [(Cp)Ru(PPh3)2Cl] (6), in the presence of NH4PF6 salt give homometallic cyano-bridged compounds of the type [(Ind)(PPh3)2Ru-CN-Ru(PPh3)2(Cp)]PF6 (7), [(Ind)(PPh3)2Ru-CN-Ru(PPh3)2(Ind)] PF6 where Ind = indenyl, η5-C9H7, (8), [(Cp)(PPh3)2Ru-CN-Ru(dppe)(Ind)]PF6, dppe = (Ph2PCH2CH2PPh2) (9), [(Ind(dppe)Ru-CN-Ru(PPh3)2(Ind)PF6 (10) and [(Ind)(dppe)Ru-CN-Ru(PPh3)2(Cp)]PF6 (11) respectively. Reaction of complex3 with [(p-cymene)RuCl2]2 dimer gave a mixed dimeric complex [(Cp)Ru(PPh3)2-CN-RuCl2(p-cymene)] (12). All these complexes have been characterized by IR,1H,13C and31P NMR spectroscopy and C, H, N analyses.
