| Abstract: | Compounds (CH3)2Sn(C12F9S)2 (I), (CH3)2Sn(C10F7S)2 (II), and (C2H5)2Sn(C10F7S)2 (III) were synthesized. Single crystals of Iwere grown and structurally characterized using X-ray diffraction analysis (1590 reflections, R = 0.0209). The crystals are orthorhombic, a = 40.848(8) Å, b = 6.058(1) Å, c = 11.183(2) Å, V = 2767(1) Å3,  (calcd.) = 2.024 g/cm3, space group Pbcn, Z = 4. The structure is built from monomeric molecules. The coordination polyhedron of the Sn atom (the SnC2S2 core) is a distorted tetrahedron. Compounds I–III are volatile when heated in vacuo. Thermolysis of these compounds results in SnO2 (in air) or SnS2 (in argon). |
