The Crystal Structure of Chlorobis(diethyldithiocarbamato)-4-ethoxyphenyltellurium(IV) Hemidioxane Solvate, [TeCl(Et2NCS2)2(EtOPh)].0.5C4H8O2.

Tris(diethyldithiocarbamato)(4-methoxyphenyl)tellurium(IV), p-MeOC6H4Te(S2CNEt2)3, and the Triclinic Modification of Tris(diethyldithiocarbamato)phenyltellurium(IV), PhTe(S2CNEt2)3

“…The same distribution of the equatorial Te--S bond lengths was found earlier in tris(dimethyldithiocarbamato)(4-methoxyphenyl)tellurium(IV), (3) (as the 1:1 chloroform solvate; Husebye, Maartmann-Moe & Steffensen, 1990), and in the monoclinic crystal modification of (2) (Esper~s & Husebye, 1972): the unique Te--S bond was the shortest [2.591 (1) and 2.606 (3)A, respective!y], the cis Te--S bonds were longer [2.646-2.706 (2)A] and the trans Te--S bonds were weaker still [2.792-2.868 (2) ~].…”

Organotellurium Compounds: From Molecular to Supramolecular Chemistry

“…The structural diversity at tellurium in the complexes is observed due to (a) strong tendency to form supramolecular associations through inter-and intramolecular Te---donor atom interactions and (b) the presence of stereochemically active lone pair at the tellurium centre. Further, Dakternieks et al [28][29][30] and others [31,32] reported supramolecular associations in organotellurium dithiocarbamates, dithiocarbonates and dithiophosphates formed through Te---S secondary interactions. These complexes have been characterized by elemental analyses, IR, ( bipyramidal.…”
