摘要：

The complex [Ru(tpy)(1)](2+) (tpy = 2,2':6',2"-terpyridine; 1 = 4'-diphenylphosphino-2,2':6',2"-terpyridine) was prepared and reacted with trans-[PdCl2(NCMe)(2)] to give trans-[PdCl2{(mu-1)Ru(tpy)}(2)](4+) in high yield. With trans-[PtCl2(NCPh)(2)], {Ru(tpy)(l)](2+) reacts to yield trans-[PtCl2{(mu-1)Ru(tpy)}(2)](4+) which isomerizes in acetone solution; equilibrium is reached after approximate to 10 days at room temperature with a 1:19 trans:cis-isomer ratio. The reaction of trans-[PtCl2(NCPh)(2)] with ligand 1 gives cis-[PtCl2(l)(2)l]. The single crystal structures of cis-[PtCl2(1)(2)]. H2O and cis-[PtCl2(1)(2)]. CH2Cl2. 1.6C(5)H(12) are described and significant differences in structure are observed dependent upon whether the solvate molecules are able to enter into hydrogen bonding interactions with the complex.
