Cyclic triorganotin dithiophosphinates of the formula (I: R = Me, II: R = t-Bu) have been synthesized by sulfur oxidation of R2Sn(H)(CH2)2P(H)Ph and Me3Sn(CH2)2P(H)Ph, respectively.With HMPT compounds I and II form the crystalline adducts III and IV.On the basis of molecular mass and spectroscopic data (Moessbauer, IR, 119Sn, 31P, and 1H NMR), solid I is suggested to have an associated polymeric structure, which breaks down in solution.Compound II is monomeric, with tetracoordinated tin, in the solid state and in non-polar solvents.An X-ray diffraction study of the HMPT adduct of I (III) reveals that the structure is monomeric and that the Sn atom is in a trigonal bipyramidal environment, with the HMPT molecule and one sulfur atom in axial positions.
