摘要：

The dialkynyl complexes cis-[Pt(C=CR)(2)L(2)] [R=Ph, L(2)=2PPh(3), 2PEt(3), dppe (dppe = 1,2-bis(diphenylphosphino)ethane]; R = (t)Bu, L(2) = 2PPh(3), dppe) react with silver perchlorate in a molar ratio 1:0.5 to give platinum-silver perchlorate salts of the type [Pt2Ag(C=CR)(4)L(4)](ClO4) in excellent yield. The X-ray crystal structure of [Pt2Ag(C=CPh)(4)(PPh(3))(4)](ClO4) 1 shows that the cation is formed by two nearly orthogonal cis-[Pt(C=CPh)(2)(PPh(3))(2)] units connected through a silver cation which is unsymmetrically pi-bonded to all four acetylene fragments. Similar reactions of cis-[Pt(C=CR)(2)L(2)] with one equivalent of AgClO4 afford cationic complexes of general formula [PtAg(C=CR)(2)L(2)](ClO4), which are believed to be salts, [Pt2Ag2(C=CR)(4)L(4)](ClO4)(2).
