A series of trimethyltin diorganothiophosphinates Me3SnOSPR'R (R'R = Me2, MePh, Ph2) was prepared from (Me3Sn)2O and R'R PSCl in cyclohexane solution.A close study of the vibrational spectra is given; 31P NMR and mass spectra are also reported.The structural investigation of Me3SnOSPMe2 by means of X-ray diffraction (R 5.2percent, 1697 observed independent reflexions) shows the compound to consists of chains, in which planar SnMe3 units and tetrahedral OSPMe2 groups are linked by the O- and S-atoms of the thiophosphinate.
