RESUMO
Molecules of diphenyl(2-thioxo-1,3-dithiole-4,5-dithiolato-S,S')plumbane, [Pb(C3S5)(C6H5)2], are linked into sheets via two intermolecular Pb...S(thione) interactions of 3.322 (4) and 3.827 (4) A; the Pb centre has a distorted octahedral geometry. In contrast, molecules of diphenyl(2-thioxo-1,3-dithiole-4,5-dithiolato-S,S')stannane, [Sn(C3S5)(C6H5)2], are linked into chains via a single intermolecular Sn--S(thione) interaction of 2.8174 (9) A; the Sn centre has a distorted trigonal-bipyramidal geometry.
RESUMO
The structure at 298 K described here, [Sn(C(6)H(5))(3)(C(7)H(4)NO(4))], completely confirms the results at 173 K obtained previously [Weng, Das & Robinson (1990), Malays. J. Sci. 12, 57]. In both structures, weak interaction between Sn and the carbonyl O atom of the benzoate group provides a distorted trigonal-pyramidal environment at the Sn atom derived from its pseudo-tetrahedral primary coordination in both molecules of the asymmetric unit.
