synthetic difficulties. Here, the structure and acid-base properties of histaminol, as well as the results of studies on its copper(II) complexes in solid state and aqueous solution are reported. Stability constants of the histaminol–CuII sys- 11 tem are measured and each stage of the complex formation is illustrated with the relevant crystal structure and the EPR spectrum.
