Notes:
The S-methyl-cis-stilbene-α,β-dithiolate of Sn(IV), Sn[Ph(S)C=C(SCH3)Ph]4, has an octacoordinate structure with two sets of four covalent and coordinate Sn-S and Sn-S(CH3) bonds of 2.425(3) and 3.599(3) Å, respectively. Both types of Sn-S bonds are close to being tetrahedral, the coordination geometry is a distorted cube. This unprecedented structure appears to involve conventional covalent and outer-sphere coordinative Sn-S bonds. In the diphenyl derivative Ph2Sn[Ph(S)C=C(SCH3)Ph]2 the SnC2S2 core formed by the covalent Sn-C and Sn-S(thiolato) bonds is tetrahedral, but two coordinate outer-sphere Sn-S(CH3) bonds of 3.500(3) Å are also present. In the related SnCl2[Ph(S)C=C(SCH3)Ph]2 the presence of the polar Sn-Cl bonds prevents outer-sphere bonding; the coordination geometry is distorted octahedral. In the triphenyltin derivative Ph3Sn[Ph(S)C=C(SCH3)Ph] the coordination geometry is tetrahedral, the thiol-thioether ligand being monodentate with the SCH3 group in a non-interactive position.
