摘要：

Seven binuclear complexes form when di-mu-hydroxo-bis(tetramethylene sulfoxide) platinum(II) reacts with di-mu-hydroxo-bis(diethyl sulfoxide)platinum(II). The seven complexes are readily observed by Pt-195 NMR and their structures are assigned. Chemical shifts and coupling constants are reported. Also observed for these dihydroxo bridged species is a significant (45 ppm) shift of the Pt-195 resonance as a function of pH suggesting a pH-dependent equilibrium which appears fast on the NMR timescale.
