    • Abstract


      Nickel-zinc hydroxy acetates with varying amounts of octahedral zinc, Ni(3-x)Zn((3-x)(OH)8(OAc)2.mH2 O, with x varying from 0 to 2, have been synthesized. The crystallographic 'a' parameter increases linearly with octahedral zinc content in the series. While the thermal stability is almost the same for the entire series of compounds, the stability of the compound in the alkaline medium increases with a decrease in octahedral zinc content. The selectivity for chloride ion from a mixture of chloride and bromide ions increases linearly with an increase in octahedral zinc content.
