摘要：

Dinuclear Pt2Br2(dPPf)(2)(mu-C8H4S2) exchanges with isonicotinic acid to release free bithiophene and gives a molecular square [Pt-4(dppf)(4)(mu(2)-O2CC5H4N)(4)](4+)4OTf(-) which is an "all-ring" system with four Pt rings disposed at the corners of a larger macrocyclic ring. The related mononuclear complex PtBr(eta(1)(C2)-C4H3S)(dppf) reacts with AgOTf (OTf = triflate) to give [Pt-2(dPPf)(2)(mu(2),eta(1)(C),eta(1)(S)-C4H3S)(2)](2+)2OTf(-) with an unusual six-membered ring formed by the fusion of two Pt-thienyl entities at the sulfur sites. All the complexes are structurally characterized by single-crystal X-ray crystallography.
