Magnetic double resonance studies of some trans-bis(triethylphosphine) complexes of platinum

Abstract

The ¹H n.m.r. spectra of 44 platinum complexes containing trans-triethylphosphine ligands, with halide, hydride, and silyl or germyl ligands, have been recorded. Heteronuclear double resonance experiments have been used to determine ³¹P and ¹⁹⁵Pt chemical shifts, as well as the signs of coupling constants, and the magnitudes of coupling constants not observed in the ¹H spectra. Systematic trends in some of the parameters enable estimates of these parameters to be made for some complexes that have not been studied.
