Abstract: | (N,N-Dimethyldithiocarbamato)(n-butyl)diphenyltin(IV), n-BuPh2SnS2NMe2, crystallizes in the monoclinic space group P21/n with a 9.772(5), b 9.895(4), c 21.418(9) Å, β 95.81(3)0, V 2060 Å3 Z = 4, μ 14.4 cm−1 The structure was determined by the heavy-atom technique from 3103 independent reflections measured at room temperature on an Enraf-Nonius four-circle CAD-4 diffractometer using monochromatized Mo-K radiation and refined to a final R value of 5.8%. The tin atom is essentially four-coordinated with a weak fifth tin-sulphur bond (Sn---S(2) 3.079(1) Å) considerably longer than the other (Sn---S(1) 2.466(1) Å). A comparison with the complex n-BuPhSn(C1)S2CNEt2 (Sn---S(1) 2.454(1) Å; Sn---S(2) 2.764(1) Å) suggests that enhanced steric factors are responsible for the preferential monodentate behaviour of the dithiocarbamate ligand in the title complex. |
