Histaminol and Its Complexes with Copper(II) - Studies in Solid State and Solution

Histaminol [4(5)-(B-hydroxyethyl)imidazole, 4-(1H-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–CuII sys- 11 tem are measured and each stage of the complex formation is illustrated with the relevant crystal structure and the EPR spectrum.
