The title compound is a novel mixed ligand and mixed valence complex of tellurium, the crystal structure of which is reported here. The compound crystallizes in the orthorhombic space group, Pca21 with four molecules per unit cell, the dimensions of which are a=15.209(1), b=20.159(2), c=12.453(1) Å. The structure was solved by the heavy-atom method and refined by fullmatrix least-squares method to a final R=0.046 and Rw=0.046 for 3011 unique reflections. The structure could be considered as 1:1 adduct of TeIVL2I2 and TeIILI (L=diisopropyldithiocarbamate). The two tellurium atoms, TeII[Te(1)] and TeIV[Te(2)] display entirely different coordinations and are bridged through iodine I(1) in a symmetrical manner. There is a short Te(1)⋯Te(2) contact distance of 3.542(1) Å. © 1989 Plenum Publishing Corporation.
