| Summary: | The crystal and molecular structures of two triphenyltin dithiocarbamates, [Sn(C6H5)3(C16H16NS2)], (I), and [Sn(C6H5)3(C7H14NO2S2)], (II), are described. In (I), the dithiocarbamate ligand coordinates the SnIV atom in an asymmetric manner, leading to a highly distorted trigonal–bipyramidal coordination geometry defined by a C3S2 donor set with the weakly bound S atom approximately trans to one of the ipso-C atoms. A similar structure is found in (II), but the dithiocarbamate ligand coordinates in an even more asymmetric fashion. The packing in (I) features supramolecular chains along the c axis sustained by C—H...π interactions; chains pack with no directional interactions between them. In (II), supramolecular layers are formed, similarly sustained by C—H...π interactions; these stack along the b axis. An analysis of the Hirshfeld surfaces for (I) and (II) confirms the presence of the C—H...π interactions but also reveals the overall dominance of H...H contacts in the respective crystals.
