Improved methods for preparing copper and zinc imidazolates, M(C3H3N2)2 (M = Zn, Cu), and their C-substituted derivatives, including copper and zinc 2-methyl-imidazolates, 2- ethylimidazolates and benzimidazolates, by reaction of a copper or zinc source with an imidazole-containing compound in aqueous media in the absence of base, and preferably in the presence of an acid. The invention also provides novel copper-zinc bimetallic imidazolates. The copper and zinc imidazolate compounds are useful as biocides and biostats and in coatings systems. |
