discussed. The [ML2](ClO4)2 complexes are 1:2 electrolytes but several show evidence for ion association. The 1H nmr spectra are reported for the complexes of the methyl substituted ligands and the coordination shifts of the methyl and vinyl protons and 3JPtH coupling are discussed. The variable temperature 1H nmr spectra show that rate of inversion at coordinated sulphur lies in the order Pt
