Isomeric dichalcogenides [Me2NCH(Me)CH2E]2 [(Nâ?/sup>E**)2] and [Me2NCH2CH(Me)E]2 [(Nâ?/sup>E*)2] (E = S, Se, Te) were obtained by the reactions of NaSH or M’2E2 (M’ = Na or K) with Me2NCH2CHMeCl. The former reaction affords mainly (Nâ?/sup>E**)2 (E = S) while from the latter mixtures of (Nâ?/sup>E**)2 and (Nâ?/sup>E*)2 [referred to as (Nâ?/sup>E)2, E = S, Se, Te] were isolated, the ratios in the mixtures depending on the chalcogen. Reactions of (Nâ?/sup>E)Na with [M2Cl2(μ-Cl)2(PR3)2] gave [MCl(Nâ?/sup>E)(PR3)] (M = Pd or Pt). These chiral, mixed-ligand complexes were characterized by elemental anal., IR, UV/visible and NMR (1H, 13C, 31P, 77Se, 125Te, 195Pt) spectroscopy, and, in part, by x-ray structure anal. The complexes display a typical pattern of mutually trans-oriented neutral (P and N) and anionic (Cl and E) donor atoms in an approx. square-planar environment. In contrast to the Pt(II) analogs, the x-ray structures of [PdCl(Nâ?/sup>E)(PMePh2)] (E = S or Se) revealed both a conformational isomerism of the five-membered chelate ring and, for Se, the co-crystallization of complexes with both the Nâ?/sup>E* and Nâ?/sup>E** isomeric ligands. The thermal behavior of some complexes was studied.
