Abstract: The square-planar complex trans-[PdCl2{Ph2PCH2S(O)Me}{MeOH}] has been prepared. The compound crystallizes as orange-red prisms in the monoclinic space group P21/n, with a = 9.446(2), b = 14.858(3), c = 13.578(3) A ̊, β = 105.08(2)° and Z = 4. The structure was determined by direct methods and refined to R = 0.027 and Rw = 0.041. All atoms including hydrogens were located directly from Fourier difference maps. The coordination geometry around palladium is square-planar. The metal is coordinated to the two chlorines, the oxygen of methanol and the phosphorus of the sulfinyl-substituted ligand. In solution, a similar structure is assigned to the complex by NMR studies. In contrast to the previously documented Ph2PCH2CH2S(O)Me analogue, the sulfoxide function in the Ph2PCH2S(O)Me ligand is not involved in any coordination bondings with palladium, both in the solid state and in solution. © 1995.
