Distinct coordination geometries in bis-[N,N-bis-(2-meth-oxy-eth-yl)di-thio-carbamato-κ(2) S,S']di-phenyltin(IV) and bis-[N-(2-meth-oxy-eth-yl)-N-methyl-dithio-carbamato-κ(2) S,S']di-phenyl-tin(IV): crystal structures and Hirshfeld surface analysis.

ABSTRACT: The crystal and mol-ecular structures of two di-phenyl-tin bis-(di-thio-carbamate)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 di-thio-carbamate 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 octa-hedral 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 supra-molecular layers in the ab plane sustai
