Heterobi- and tri-metallic compounds containing a Cp2Ti(IV unit linked via nicotinate, thiophenoxyacetate or diphenylphosphinoacetate ligands to Pd, Pt, Cu, Ag or Au centres have been isolated. They are of the types [ Cp2Ti {μ-OC (O) R }2MCl2 ] (M = Pd, R = m-C5H4N, CH2SPh and CH2PPh2; M=Pt, R=m-C5H4N or CH2PPh2), [Cp2Ti{μ-OC(O)CH2PPh2}2(M'Cl)2] (M' =Cu or Au) and [Cp2Ti{μ-OC(O)CH2PPh2}2AgCl]. The diphenylphosphinoacetate products arise both from methane elimination reactions of [Cp2TiMe2] with either [MCl2(Ph2PCH2CO2H)2] or [M'Cl (Ph2PCH2CO2H)] and from reactions of [Cp2Ti {OC(O)CH2PPh2}2] with metal complexes containing labile ligands. Crystal structures of [Cp2Ti{OC(O)CH2PPh2}2] and [Cp2Ti{μ-OC(O) CH2PPh2}2PdCl2] are discussed. The latter compound contains diphenylphosphinoacetate groups which are O-unidentate with respect to titanium and P-unidentate with respect to palladium, the result being the formation of a ten-atom heterobimetallic ring system.
