N-Benzyl-N-(2-phenyl­eth­yl)di­thio­carbamato-κ2SS′tri­phenyl­tin(IV) and bis­(2-meth­oxy­eth­yl)di­thio­carbamato-κ2SS′tri­phenyl­tin(IV): crystal structures and Hirshfeld surface analysis

摘要

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 Sn^IV 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.
