摘要：

Reaction of [Ir(C5Me5)(SRF)2] (R(F) = C6F5 la or C6F4H-p lb) with K2[PtCl4] gave trinuclear complexes [Ir2Pt(C5Me5)2(mu-SRF)4Cl2] (R(F) = C6F5 2a or C6F4H-p 2b). Complexes 2a and 2b were characterized by single-crystal X-ray determinations. The structures are very similar and show short contact interactions between the platinum and the o-F of the bridging perfluorobenzenethiolate groups. Variable-temperature F-19 NMR spectra of solutions of complexes 2a and 2b reveal the coexistence of several conformers without the Pt...o-F short contact found in the solid state.
