Crystal and Molecular Structure of Chlorotris[bis(2-hydroxyethyl)dithiocarbamato]tellurium(IV) Dihydrate

The synthesis, properties, and crystal structure of the unusual mixed-ligand complex TeCl [(HOC2H4)2NCSS] 3-2H2O are described. The complex is monomeric in the crystalline state. The molecular structure shows a highly distorted pen-tagonal-bipyramidal coordination around tellurium featuring both strong and weak Te-S bonds in the equatorial plane and a strong Te-S bond and a rather weak Te-Cl bond in the axial positions. The complex is less stable than tetrakis-(diethyldithiocarbamato)tellurium(IV). The chlorine atom and all the oxygen atoms participate in hydrogen bonding, and the packing arrangement in the unit cell seems to be mainly dictated by the hydrogen-bonding network. © 1983, American Chemical Society.
