Synthesis and characterization of di-and triorganotin(IV) diethyldithiophosphinates. The crystal and molecular structure of bis(diethyldithiophosphinato)dimethyltin(IV), Me2Sn(S2PEt2)2
spectrosopy. The probable structure of the new compounds was inferred from the spectral data. The crystal and molecularstructure of Me2Sn(S2PEt2)2 has been determined by X-ray diffraction. The compound is monoclinic space group C′2/c, with a 20.814(11), b 6.243(3), c 16.092(8) Å, 105.42(8)°, Z = 4, Dx 1.500 g cm−3. The molecule exhibits a distorted tetrahedral environment around tin, with angles CSnC
