Abstract

The effect of pyridine addition upon the gas-phase reactions of hydrogen sulphide (H2S) with dimethylzinc (Me(2)Zn) in the presence of pyridine has been investigated and compared with results from reactions of H2S with Me(2)Cd. The deposits of ZnS which form have been analysed and consist of particles in the nanocrystalline size range of mainly the hexagonal phase. The average particle size within the deposits depends on both the concentration of pyridine in the gas phase and the temperature at which the reactants are mixed. Pyridine may bind through the lone pair of the nitrogen to surface metal atoms of growing particles, inhibiting further growth of the particle.
