摘要:
The title mixed ligand complex was synthesized by the controlled oxidative displacement reaction of TeL4" by iodine (L" is diisopropyldithiocarbamate ion). Its crystals are monoclinic, space group P2l with Z = 2 in a unit cell of dimensions a = 8.344(4), b = 14.113(8), c = 10.647(5) angstron, beta = 99.884(2)-degrees, and V = 1235.15 Angstron 3, final R = 0.043 and R(w) = 0.047 for 3553 unique reflections. The central tellurium atom shows a S4I2 six coordination with the two dithiocarbamate groups almost isobidentate, the average Te-S and the Te-I distances being 2.571(3) and 3.011(1) angstron, respectively. The structure is monomeric in the solid state. No intermolecular short contacts are observed.
