Heterobimetallic complexes of platinum with silver, gold, mercury, or cadmium bridged by Ph 2 PCH 2 PPh 2 : crystal structure of [(PhCC) 2 Pt(µ-Ph 2 PCH 2 PPh 2 ) 2 AgI]

The η1-Ph2PCH2PPh2(dppm) complexes [Pt(CCR)2(η1-dppm)2](R = Ph, p-tolyl, or Me) are used to give high-yield syntheses of heterobimetallic complexes with AgI, AuI, HgII, or CdII, in which the d10-metal can be 2-, 3-, or 4-co-ordinate.
