Crystal structures and Hirshfeld surface analyses of (N-hexyl-N-methyl­dithio­carbamato-κ2SS′)triphenyl­tin(IV) and N-methyl-N-(2-phenyl­ethyl)­dithio­carbamato-κ2SS′tri­phenyl­tin(IV)

摘要

The crystal and mol­ecular structures of two tri­phenyl­tin di­thio­carbamate compounds, viz. [Sn(C6H5)3(C8H16NS2)], (I), and [Sn(C6H5)3(C10H12NS2)], (II), are described. The di­thio­carbamate ligand in each mol­ecule coordinates in an asymmetric fashion resulting in heavily distorted tetra­hedral C3S coordin­ation geometries for the Sn atoms, with the distortions traced to the close approach of the non-coordinating thione-S atom. The mol­ecular packing in both compounds features C—H⋯π(Sn-phen­yl) inter­actions. In (I), the donors are Sn-phenyl-C—H groups leading to centrosymmetric aggregates, while in (II), the donors are both Sn-phenyl-C—H and methyl-C—H groups leading to supra­molecular chains propagating along the b axis. The identified aggregates assemble into their respective crystals with no directional inter­actions between them. An analysis of the Hirshfeld surfaces show distinctive patterns, but an overwhelming predominance (>99% in each case) of H⋯H, C⋯H/H⋯C and S⋯H/H⋯S contacts on the respective Hirshfeld surface.
