Crystal structures and Hirshfeld surface analyses of (-hexyl--methyl-dithio-carbamato-κ,')triphenyl-tin(IV) and [-methyl--(2-phenyl-ethyl)-dithio-carbamato-κ,']tri-phenyl-tin(IV).

The crystal and mol-ecular structures of two tri-phenyl-tin di-thio-carbamate compounds, . [Sn(CH)(CHNS)], (I), and [Sn(CH)(CHNS)], (II), are described. The di-thio-carbamate ligand in each mol-ecule coordinates in an asymmetric fashion resulting in heavily distorted tetra-hedral CS coordin-ation geometries for the Sn atoms, with the distortions traced to the close approach of the non-coordinating thione-S atom. The mol-ecular packing in both compounds features C-H⋯π(Sn-phen-yl) inter-actions. 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 supra-molecular chains propagating along the axis. The identified aggregates assemble into their respective crystals with no directional inter-actions 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.
