By the reactions of Pd²⁺, thiolate (PhCH₂S^- or pdt) and dppe or dppp [pdt = SCH₂CH₂CH₂S^2-, dppe = 1,2-bis(diphenylphosphino)ethane, dppp = 1,3-bis(diphenylphosphino)propane] in MeOH, the following complexes, [Pd(SCH₂Ph)₂(dppe)] (1), [Pd(SCH₂Ph)₂(dppp)] (2) and [Pd(pdt)(dppp)] (3), were prepared. The crystal structure of 2 was analysed by single-crystal X-ray diffraction. The palladium atom is tetra-coordinated with a distorted square-planar geometry of two phosphorus and two sulfur atoms. Their IR, ³¹P and ¹H NMR spectra are reported.
