Crystal structure of [NN′-tetramethylenebis(thioacetylacetoniminato)(2–)]zinc

The title compound crystallises in space group C2/c, with a= 12·286(10), b= 11·970(10), c= 12·608(10)A, β= 120·67(5)°, and Z= 4. The structure was solved by the heavy-atom method from diffractometer data and refined by least-squares methods to R 0·097 for 1056 reflections. The structure consists of discrete molecules lying on the two-fold rotation axes, and the ligand is folded to give pseudo-tetrahedral co-ordination about the zinc atom.
