New complexes of zinc(ii) and copper(ii) with 2-furoic acid (Hfur), acetic acids and N-donor ligands with the compositions [Zn2 (fur)4 ] n (1), [Zn2 (fur)4 (NH2 py)2 ] (2, NH2 py = 3-aminopyridine), [Zn(fur)2 (neoc)] (3, neoc = 2,9-dimethyl-1,10-phenantroline), [Zn(OAc)2 (neoc)] (4, OAc = acetat-anion), and [Cu(fur)2 (neoc)(H2 O)] (5) were synthesized. The structures of the compounds were established by single crystal X-ray diffraction analysis. Complexes 1 and 2 are binuclear; whereas 3-5 are mononuclear. The stabilization of supramolecular architectures in crystals for compounds 1-5 occurs due to π-π-bonding between heterocycles and hydrogen interactions that provide good solubility in aqueous solutions...
