Abstract
Seven binuclear complexes form when di-μ-hydroxo-bis(tetramethylene sulfoxide)platinum(II) reacts with di-μ-hydroxo-bis(diethylsulfoxide)platinum (II). The seven complexes are readily observed by 195Pt 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 195Pt resonance as a function of pH suggesting a pH-dependent equilibrium which appears fast on the NMR timescale.
