Structural studies of metal dithiocarbamates. Part VI. The crystal and molecular structure of tetrakis(NN-diethyldithiocarbamato)titanium(IV)

Abstract

The crystal and molecular structure of the title compound has been determined from data measured on a manual diffractometer. Crystals are triclinic, space-group P, with a= 11·435, b= 18·408, c= 15·382 Å, α= 96·39, β= 91·62, γ= 95·08°, and Z= 4. The structure has been refined by least-squares, with anisotropic temperature factors to a final R of 0·097. In each molecule the titanium atom is eight-co-ordinated by the sulphur atoms from four chelating dithiocarbamate ligands. The co-ordination geometry approximates very closely to dodecahedral, with chelation along the m edges, giving the D_2d isomer. The two symmetry-unrelated molecules in the unit cell are identical, within the limits of experimental error, except for minor conformational differences which can be attributed to packing forces.
