摘要：

The title compound Te(II)LI [L = diethyl dithiocarbamate, (C2H5)2NCS2-] was synthesized by the reduction of Te(IV)L2I2 with elemental tellurium. Its structure has been determined and is found to be polymeric, with I being the bridging ligand. The polymeric chain adopts a helical configuration which runs parallel to the c-axis of the tetragonal unit cell. Each tellurium is bonded to two sulphurs of a chelating dithiocarbamate group and to two iodines in a planar configuration. The bond distances of Te-S(1), Te-S(2), Te-I and Te-I' are 2.536(4), 2.483(5), 3.108(1) and 3.279(1) angstrom, respectively, and the bond angles of I-Te-S(1), S(1)-Te-S(2), S(2)-Te-I' and I'-Te-I are 149.6(2), 70.7(2), 151.1(2) and 129.2(2)-degrees, respectively.
