All complexes were characterized by elemental anal., IR and NMR (1H, 13C, 31P, 77Se, 195Pt) spectroscopy. The stereochem. of these complexes was deduced from the NMR spectroscopic data and the structure of [Pd(SeCH2CH2CH2NMe2)Cl]2 was established by single crystal x-ray diffraction anal. Each Pd atom in the dimer is surrounded by two \textgreek{m}-Se atoms, a N atom and a chloride ligand.

[except for (mmb)PtMe2] and by 1H and 195Pt NMR spectroscopy. The tetramethylplatinum(IV) complexes exhibit a variable degree of dynamic 1H NMR behavior due to the mobility at the thioether S atom in the nonplanar five-membered chelate ring, as supported by structural anal. D.-functional theory (DFT) calcns. were used to reproduce the structural features and the 1H NMR chem. shifts. In comparison with other late transition metal complexes of these N-S chelate ligands the Me4Pt and esp. the Me2Pt compds. exhibit a relatively stronger preference of the metal for the S donor.
