Abstract
The effect of pyridine upon the gas-phase reaction of dimethylcadmium (Me(2)Cd) with hydrogen sulfide (H2S) has been investigated. Analysis of the solid reaction product by powder X-ray diffraction (PXRD), elem ental analysis (EA) and transmission electron microscopy (TEM) reveals the deposit to consist of crystalline CdS particles in the nanometre size range of the Greenockite (hexagonal) phase, with pyridine molecul es bound to surface cadmium atoms. The average particle size within th e deposit is dependent upon both the concentration of pyridine in the gas phase and the temperature at which the gas-phase reactants are mix ed.
