Abstract

The crystal and mol­ecular structures of two di­phenyl­tin bis­(di­thio­carbamate)s, [Sn(C6H5)2(C5H10NOS2)2], (I), and [Sn(C6H5)2(C7H14NO2S2)2], (II), are described. In (I), in which the metal atom lies on a twofold rotation axis, the di­thio­carbamate ligand coordinates with approximately equal Sn-S bond lengths and the ipso-C atoms of the Sn-bound phenyl groups occupy cis-positions in the resulting octa­hedral C2S4 donor set. A quite distinct coordination geometry is noted in (II), arising as a result of quite disparate Sn-S bond lengths. Here, the four S-donors define a trapezoidal plane with the ipso-C atoms lying over the weaker of the Sn-S bonds so that the C2S4 donor set defines a skewed trapezoidal bipyramid. The packing of (I) features supra­molecular layers in the ab plane sustained by methyl­ene-C-H...[pi](Sn-ar­yl) inter­actions; these stack along the c-axis direction with no specific inter­actions between them. In (II), supra­molecular chains along the b-axis direction are formed by methyl­ene-C-O(ether) inter­actions; these pack with no directional inter­actions between them. A Hirshfeld surface analysis was conducted on both (I) and (II) and revealed the dominance of H...H inter­actions contributing to the respective surfaces, i.e. >60% in each case, and other features consistent with the description of the mol­ecular packing above.
