SYNTHESIS AND CRYSTAL-STRUCTURE OF DIMETHYLDI(MONOTHIOBENZOATO)TIN(IV)

The reaction of dimethyltin(IV) dichloride with monothiobenzoic acid r esults in the formation of dimethyldi(monothiobenzoato)tin(IV), C16H16 O2S2Sn, which crystallizes in the orthorhombic system, space group Cmc 2(1), Z = 8, a = 20.578(7), b = 7.409(4) and c = 11.270(4) angstrom. R efinement converged to R = 0.030 and R(w) = 0.032 based on 1079 unique reflections such that 3.0-degrees less-than-or-equal-to 2THETA less-t han-or-equal-to 55.0-degrees. Each of the two ligands functions as a m onodentate anion coordinating to the tin atom through its sulfur atom and conferring a tetrahedral geometry about the tin atom.
