Reaction of [PtPh2(cod)] or [PtClPh(cod)] with (Ph2PC5H4)2ZrCl2 yields the Ph2PC5H4-bridged species [PtXPh(Ph2PC5H4)2ZrCl2] (X = Ph, Cl). Treatment of [PtPh2(cod)] or [PtClPh(cod)] with 2 equiv of PhP(C5H4)2ZrCl2, prepared by reaction of [ZrCl4(THF)2] with (TlC5H4)2PPh, yields cis- [PtPh2{PhP-(C6H4)2ZrCl 2}2] or trans-[PtClPh{PhP(C5H4)2ZrCl2} 2]. Each of the mixed-metal complexes has been isolated as an air-sensitive solid and characterized by elemental analysis and NMR spectroscopy. [PtPh2-(Ph2PC5H4) 2ZrCl2] does not react with carbon monoxide, and cis-[PtPh2{PhP(C5H4)2ZrCl 2}2] undergoes a slow displacement of phosphine by CO, whereas the two chlorophenylplatinum complexes undergo smooth carbonylation to the corresponding benzoylplatinum species.
