Three new organotin(IV) structures of general formula RSn(S CN ′ ″) Cl, where ′ ≠ ″, namely MeSn · [S CN(Me)(Cy)] Cl ( ), MeSn[S CN( -Pr)(CH Ph)] Cl ( ) and PhSn[S CN(Et)( -Pr)] Cl ( ) are described. Each structure features tin in a distorted octahedral geometry defined by a C S donor set as a result of two chelating dithiocarbamate ligands. In all cases the tin-bound carbon and chloride atoms are . The shorter Sn–S bond lengths in are correlated with the presence of the relatively more electronegative Sn-bound phenyl substituent. The new structures conform to the structural motif adopted by all other compounds with the formula RSn(S CN ′ ″) Cl, where ′ = ″, suggesting the unsymmetrical substitution pattern of the dithiocarbamate ligands in the present study does not influence the adoption of this structural motif. The homogeneity in the structural motif notwithstanding, non-systematic variations in geometric parameters are found in these structures indicating an overall influence of crystal packing upon molecular geometry.
