  Stability constants were determined for a series of coordination complexes of Mn(II), Co(II), Ni(II), Zn(II) and Cd(II) with histaminol in aqueous solution. The tendency of histaminol to form chelate complexes has been confirmed by the isolation of several complex species in the monocrystalline form and determination of their molecular structures.

  - Year 2019

  Rozprawa doktorska porusza zagadnienia związane z syntezą oraz właściwościami związków koordynacyjnych metali przejściowych z pochodnymi imidazolu. Główna uwaga poświęcona jest 4(5)-(β-hydroksyetylo)imidazolowi — występującemu naturalnie ligandowi, będącemu hydroksylowym analogiem histaminy, o zwyczajowej nazwie histaminol. Praca skupia się na ligandach zbliżonych strukturalnie do 4(5)-(β-hydroksyetylo)imidazolu oraz wykazującymi...

  - EUROPEAN JOURNAL OF INORGANIC CHEMISTRY - Year 2018

  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...

  - INORGANICA CHIMICA ACTA - Year 2017

  Two dinuclear complexes of zinc and cadmium with silanethiolate and bridging biimidazole ligands are characterized by X-ray diffraction, FT-IR, UV–Vis and emission spectroscopies. The complexes 1 (Zn) and 2 (Cd) are isostructural but exhibit different electronic structures and different character of frontier HOMO orbitals as indicated by DFT calculations. Lluminescence studies prove strong emission properties of zinc complex.
