BILC, Danut et al. New Palladium(II) Tetraorganodichalcogenoimido Diphosphinates. Crystal and Molecular Structure of Pd[(SPMe₂)₂N]₂ and cis-Pd[(OPPh₂)(SPMe₂)N]₂. Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.2, pp.116-121. ISSN 0583-7693.

Bis(tetraorganodichalcogenoimidodiphosphinato)palladium(II), Pd[(XPR₂)(YPR'₂)N]₂, were prepared and investigated by means of IR and multinuclear (¹H, ¹³C, ³¹P) NMR spectroscopy. The crystal and molecular structures of Pd[(SPMe₂)₂N]₂ (1) and cis-Pd [(OPPh₂)(SPMe₂)N]₂ (2) were determined by X-ray diffractometry. The crystals of both compounds contain discrete mononuclear molecules. The ligands act as monometallic biconnective units through both chalcogen atoms which results in a spiro-bicyclic system with distorted square planar PdS₄ and PdS₂O₂ core, respectively.
