摘要：

The structure of the title compound, [TeCl4(C5H10N2S)(2)] or C10H20Cl4N4S2Te, has been solved in order to study the stereochemical activity of the lone pair of electrons on Te-IV. The two crystallographically independent molecules in the asymmetric unit both show a distorted octahedral coordination of the Te atom. The two Te-S bonds are trans to each other in both molecules and are greatly asymmetric, with bond lengths of 2.5686 (7) versus 2.8557 (8) Angstrom and 2.5859 (7) versus 2.8165 (9) Angstrom. The Te-Cl bond lengths lie in the range 2.5236 (7)-2.5589 (8) Angstrom. The asymmetric Te-S bonds and a large S-Te-Cl angle of ca 97 degrees involving the long Te-S bonds indicate stereochemical activity of the lone pair of electrons on Te.
