The crystal structure of trimethyltin isothiocyanate

The crystal structure of Me3SnNCS has been determined by single crystal X-ray diffraction. The crystals are orthorhombic, Pbca, a = 13.20(1), b = 10.28(1), c = 12.01(1) Å, Z = 8. The molecules are arranged in infinite zig-zag SSnNC SSn chains, linear except at sulphur. The principal bond lengths and angles are: SnN,2.15(6); NC, 1.15(7); CS,1.64(7); SSn, 3.13(2); SnC(H3) (mean), 2.13(3); angle NSnC(H3) (mean), 95(2)° and angle CSSn, 97(2)°.
