Copper(II) complexes of carvedilol molecule, (carvH): 1-[carbazolyl-(4)-oxyl]-3-[(2-methoxyphenoxyethyl)-amino]-2-propanol, were synthesized and characterized with respect to their structural and spectroscopic properties. The crystal structure of [Cu(Carv)Cl(MeOH)]2•4MeOH complex revealed that the molecule chelates two Cu(II) ions via the N and O atoms belonging to the amino and propanol moiety, respectively. The coordination behaviour of carvedilol studied by 1H nuclear magnetic resonance (NMR, 1-D and 2-D-COSY) spectroscopy in dimethyl sulfoxide solution at room temperature, allowed us to obtain structural information and to identify the donor atoms involved in the coordination process in solution.
