摘要: Abstract Di- and tri-organotin(IV) dimethyldithiophosphinates, R 2 Sn(S PMe ) (R = Me, n-Bu, Bz, Ph) 3 SnS Cy, were prepared by treating the corresponding organotin chlorides with sodium dimethyldithiophosphinate. All compounds characterized infrared 1 H NMR spectra. For two representative derivatives, i.e. Me Ph , 119m Sn Mossbauer spectra mass also investigated. Monodentate coordination of dithiophosphinato ligand tetrahedral structures are proposed for triorgano-tin derivatives. In diorganotin geometry around tin is intermediate between (with monodentate ligands) octahedral anisobidentate ligands). The CSnC bond angle values calculated on basis J ( 119 SnC H), 128.4°, or QS value, 126.8°, compare satisfactorily that obtained X-ray diffraction, 122.6°.
