6,6-Diphenyl-6,7-dihydro-5H-1,3,4,8-tetrathia-6-stannazulene-2-thione and 6,6'-spirobi[6,7-dihydro-5H-1,3,4,8-tetrathia-6-stannazulene]-2,2'-dithione.
The title compounds, [Sn(C(6)H(5))(2)(C(5)H(4)S(5))] and [Sn(C(5)H(4)S(5))(2)], respectively, are of interest because they can be regarded as intermediate in nature between chelates and heterocyclic compounds containing the C(3)S(5) fragment. In contrast with the essentially normal bond lengths and angles within the molecules, the molecular conformations are somewhat unexpected, as are the intermolecular contacts found in the case of the latter compound.
