Five new ternary metal complexes containing imidazole and glycylglycine or amino acid have been prepared and characterized by proton magnetic resonance and infrared spectral studies. Seven new binary metal complexes have also been prepared and studied. The isolation of Cd(imidazole)6Cl2•H2O and Ni(imidazole)6-Cl2•4H2O provides evidence that the coordination number of these metal ions to imidazole in the solid state is six. The visible spectra of the Ni(II) complexes of amino acid and imidazole show that all these are octahedral in aqueous solution.

Thin films (2.0 nm) of copper on germanium internal reflection elements (IREs) were exposed to 10% gum arabic (aqueous solution), 2% alginic acid (aqueous solution), 1% bacterial culture supernatant (BCS, simulated seawater solution), and 0.5% Pseudomonas atlantica exopolymer (simulated seawater solution) and monitored in situ, real time, with the use of Fourier transform infrared/cylindrical internal reflection/attenuated total reflection spectroscopy as a function of time at ambient conditions. Ancillary graphite furnace atomic absorption spectroscopy was used to monitor the removal process of the copper thin film from the germanium IREs. Results indicate that some of the copper was removed from the Cu/Ge interface by all four polymers and incorporated into the polymer matrix. Thus, biocorrosion of copper was exhibited by the four polymers in the order of alginic acid < gum arabic < BCS > Pseudomonas atlantica exopolymer. The FT-IR/CIR/ATR technique can be successfully used to monitor biocorrosion systems in in situ, real-time settings.
