Synthesis and Crystal Structure of a Dimethyltin Derivative of 1,4-Dithioerythritol

Abstract

The title complex, [(CH3)2(HOC2H5)Sn(C4H6O2S2)Sn(HOC2H5)(CH3)2], was synthesized starting from dimethyltin dichloride, 1,4-dithioerythritol and sodium ethoxide. The crystal structure was determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n with a = 7.9282(6)A, b = 11.3888(9)A, c = 11.0228(9)A, β = 99.594(3)°, Z = 2, V = 981.36(13)A3. Its crystal structure was determined and refined to a final R = 0.0232 for 1730 independent reflections. The complex is the symmetric dinuclear unit made up of two distorted trigonal bipyramids.
