Abstract: | 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 P21 withZ=2 in a unit cell of dimensionsa=8.344(4),b=14.113(8),c=10.647(5) Å,=99.884(2)°, andV=1235.15 Å3, finalR=0.043 andRw=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) Å, respectively. The structure is monomeric in the solid state. No intermolecular short contacts are observed. |
