Description:
Benzotriazole (bta-H) is a well-known corrosion inhibitor for copper, copper-alloy, and other metal surfaces. Typical uses are to deactivate surfaces of computer hard drives and other internal metal computer parts, and for treatment of apparel hardware such as zippers and buttons to withstand harsh fabric washing and dyeing processes. Particles from these surface treatments will ultimately contribute to environmental indoor dust or outdoor industrial effluent, but they have not ben fully characterized. Bta-H is one of a group of several organic ligands which bind to transition metals and which have similar structures. We have systematically investigated approximately 30 transition metal complexes of the general formula ML2, where M=VO2+, Mn2+, Co2+, Ni2+, Cu2+, and Zn2+, and L=deprotonated benzotriazole, imidazole, benzimidazole, 2-methylimidazole, or 2-methylbenzimidazole. Where possible, these materials have been synthesized and characterized by chemical analysis, spectroscopy, and x-ray diffraction techniques. The ML2 compounds are coordination polymers with metal-deprotonated nitrogen and metal-nitrogen (dative bonding) interactions. X-ray powder deffraction patters have been determined and indexed for Co(C3N2H3)2 * H2O and Zn(C3N2H3)2 * 0.5 H2O.
