| Abstract |
Reactions of carbamodithiolate salts viz., c-C3H5NH3+(L-2)(-) and c-C6H11 NH3+(L-2)(-) (L-1 = cyclopropy-lcarbamodithioate, L-2 = cyclohexylcarbamodithioate) with R2SnCl2 (R = Me or n-Bu) were investigated in dichloromethane for the first time. A series of four diorganotin(IV) complexes of composition [Me2Sn(L-1)Cl] (1), [Me2Sn(L-1)(2)] (2), [Me2Sn(L-2)(2)] (3) and [n-Bu2Sn(L-2)(2)] (4) were isolated and characterized by spectroscopic methods. The structures of the two carbamodithiolate salts and the diorganotin(IV) compounds 1-4 were accomplished by X-ray crystallographic analysis revealing distorted square pyramid geometry for 1, but skewed trapezoidal bipyramids for 2-4. Influence of the carbamodithiolate moiety on the hydrogen-bond interactions and non-covalent contacts, as well as on the packing of the structures, is discussed. The 3D Hirshfeld surfaces were mapped and used to study the intermolecular interactions. (C) 2020 Elsevier B.V. All rights reserved. |
