Histaminol [4(5)‐(β‐hydroxyethyl)imidazole, 4‐(1 H ‐imidazol‐2‐yl)ethanol, L] is an analogue of histamine and its minor metabolite. So far its properties have not been studied in detail due to the 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–Cu II system are measured and each stage of the complex formation is illustrated with the relevant crystal structure and the EPR spectrum.
