Heterodinuclear platinum (or palladium) complexes having a terminal carbene, (Ph3P)Cl(Me2- NHC)M-M′L′n (M = Pt:M′L′ n = Co(CO)4 (1), Mn(CO) 5 (2), MoCp(CO)3 (3), FeCp(CO)2 (4); M = Pd: M′L′n = Co(CO)4 (33), Mn(CO)5 (34)) and (L)Cl{(PhCH2)YC}Pt-M'L'., (WVn = Co(CO)4, L = PMe2Ph: Y = NPh2 (5), OEt (6), OMe (7), OiPr (8); M′L′n = Co(CO)4, L = PPh3: Y = OEt (9); M′L′n = Mn(CO)5, L = PMe2Ph: Y = OEt (10)), are synthesized by metathesis reactions of dichlorocarbene complexes with metalate Na+[M′L′ n]-. These complexes are characterized by NMR and IR spectroscopies and elemental analysis, and the molecular structures of 1, 2, and 6 are determined by X-ray structure analysis. Deprotonation of 6-10 with base gives heterodinuclear μ-alkoxystyrylplatinum-metal complexes, (L)(CO){μ-PhHC=YC}Pt-M′L′.,n-1 (M′L′ n-1 = Co(CO)3, L=PMe2Ph: Y = OEt (13), OMe (14), OiPr (15); M′L′n-1 = Co(CO)3, L = PPh3: Y = OEt (16); M′L′.,n-1 = Mn(CO)4, L = PMe2Ph: Y = OEt (12)), where the E isomer is thermodynamically stable. Z isomers of corresponding monomelic alkoxystyrylplatinum(II) complexes are found to be more stable than the corresponding E isomers. In contrast, both the dinuclear diphenylaminostyrylplatinum-cobalt complex and its mononuclear analogue favor the Z configuration.
