The synthesis, full characterization, and molecular structures of seven new coordination compounds that feature the 2-(4',4'-dimethyloxazolin-2'-yl)thiophenolate ligand (S-Phoz) with group 10 metals Ni, Pd, and Pt in the +II oxidation state are presented. The ML2 complexes [Pt(S-Phoz)(2)] (1a), [Pd(S-Phoz)(2)] (1b), and [Ni(S-Phoz)(2)] (2) were prepared starting from MCl2. Compound 1a was obtained isomerically pure in a trans arrangement, whereas its Pd analogue 1b exhibits a dynamic, solvent-dependent cis/trans equilibrium, and 2 adopts a tetrahedral arrangement. The reaction of LiS-Phoz with [cis-MCl2(PPh3)(2)] precursors resulted in full replacement of the PPh3 for M = Ni and in partial substitution for M = Pt, Pd to yield [Ni(S-Phoz)(2)] (2), [Pt(kappa(2)-S-Phoz)(kappa(1)-S-Phoz)-(PPh3)] (3a), and [Pd(kappa(2)-S-Phoz)(kappa(1)-S-Phoz)(PPh3)] (3b). The Pd compound 3b exhibits an interesting solvent-dependent equilibrium with 1b and PPh3 as demonstrated by H-1 and P-31 NMR spectrosco...py. Compounds [{PdCl(S-Phoz)}(2)] (4) and [PdCl(S-Phoz)(PPh3)] (5) were synthesized from [PdCl2(NCMe)(2)]. Molecular structures of compounds trans-1a, trans-1b, 2, 3a, 3b, 4, and 5 were determined by singlecrystal X-ray diffraction studies. With the exception of the Ni complex 2, all compounds exhibit distorted square-planar geometries.
