Abstract
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.
