(4), Cp(PPh3)Ru(μ-Cl)(μ-dppm)Pd(CH3)Cl (5), Cp(PPh3)Ru(μ-I)(μ-dppm)PtCl2
(6), Cp(PPh3)Ru(μ-I)(μ-dppm)PtI2
(7), Cp(PPh3)RuI(μ-dppm)AuI (8), Cp(PPh3)RuBr(μ-dppm)AuCl (9), Cp(PPh3)RuCl[μ-PPh2(CH2)4PPh2]AuCl (10), Cp(PPh3)RuCl(μ-Ph2PNHPPh2)AuCl (11) and Cp(PPh3)Ru(μ-I)(μ-dppm)CuI (12) were prepared by the reactions of CpRu(PPh3)(η1-Ph2PQPPh2)X [Q =
