Synthesis and anion exchange reactions of a layered copper–zinc hydroxy double salt, Cu1×6Zn0×4(OH)3(OAc)×H2O

A mixed-metal hydroxysalt of formula Cu1-6 Zn o-4(H)3(OAc) H2O has been synthesized by an acetate hydrolysis route. Acetate ions can be exchanged with simple inorganic anions such as chloride and nitrate, and organic anions such as benzoate and large surfactant anions such as dodecyl sulphate. Structures of these hydroxysalts are derived from that of Cu2(OH)3NO3H2O with some of the Cu2+ ions being replaced by Zn2+.
