PREPARATION AND CHARACTERIZATION OF SEVERAL GROUP-12 ELEMENT (ZN,CD)-BIS(THIOLATE) COMPLEXES AND EVALUATION OF THEIR POTENTIAL AS PRECURSORS FOR 12-16 SEMICONDUCTING MATERIALS

Compounds of the general formula M(SR)(2) (M = Zn, Cd; R = i-Pr, t-Bu, Bz) have been prepared and explored as potential unimolecular startin g materials for the preparation of binary group 12 metal sulfides. The se new compounds have been characterized by IR spectroscopy and thermo gravimetric analysis. Chemical derivatization of these insoluble metal -bis(thiolate) compounds by complexation with N-CH3-imidazole renders them more soluble. These adducts were investigated by elemental analys is. Thermolytic decompositions of both the parent and derivatized comp ounds have been carried out both in the solid state and by heating a s uspension of the appropriate metal-bis(thiolate) compound in an inert high boiling hydrocarbon medium: The thermolysis products have been st udied by GC/MS (liquids) and x-ray powder diffraction (XRPD), scanning electron microscopy (SEM), and particle size determination (solids).
