Abstract. Orthorhombic, P212121, Z=4, 2(CuKa)

The title compound crystallizes in the monoclinic space group P21/c with Z=4 and cell dimensions a=7.724(1), b=19.274(5), c=18.638(4)~, and ---105.68(2) ~ . Refinement with 1126 terms, measured with Mo K~ radiation on a diffractometer, has yielded a conventional R factor of 0.059. The nonhydrogen atoms in the complex molecule were refined with anisotropic temperature factors whereas those in the acetone molecule were refined isotropically. The nitrogen atoms in the complex are not coordinated; the coordination sphere involves Co-$6 bonding of approximate D3 symmetry, the average Co-S bond length being 2.275 ~. The geometry of the coordination sphere with respect to a defined C3 reference axis is similar to that found in several tris (N,N'-disubstituted-dithiocarbamato)The acetone molecule is hydrogen bonded to one of the amino groups, the O, 9 9 N distance being 2.99 ~.
