摘要：

Terminal organotransition-metal acetylides trans-[Pt(C=CR)2L2] (R = Ph or Bu(t), L = PPh3 or PEt3), cis-[Pt(C = CBut)2L2] (L = PPh3 or PEt3), (Pt(C=CR)2(dppe)] (R = Bu(t) or SiMe3, dppe = Ph2PCH2-CH2PPh2) and [Au(C = CR)(PPh3)] (R = Ph or Bu(t)) reacted with cis-[Pt(C6F5)2(CO)(thf)] (thf = tetrahydrofuran) to give, under alkynylation of the fragment Pt(C6F5)2(CO), the mu-eta2-acetylide-bridged dinuclear zwitterionic complexes [(OC)(C6F5)2Pt-(mu-eta2-C = CR)M+Ln]. The phenylacetylide complex [(OC) (C6F5)2Pt-(mu-eta2-C = CPh)Pt+(C = CPh)(PPh3)2] has been characterised by X-ray structural analysis.
