The Uses of Benzotriazole-5-carboxylic acid
Benzotriazole-5-carboxylic acid was used as bifunctional ligand in solvent induced synthesis of diverse dimensional coordination assemblies of cupric benzotriazole-5-carboxylate. It was also used in hydrothermal synthesis of new coordination polymer, [Zn(Btca)(Phen)]n (H2Btca = benzotriazole-5-carboxylic acid, Phen = 1,10-phenanthroline).
