Abstract: | Two 2D complexes, Co(mal)(phen)(H2O)2] (1) and Ni(mal)(phen)(H2O)2] (2) (mal?=?malonate dianion; phen?=?1,10-phenanthroline), have been synthesized by the reaction of Co(ClO4)2·6H2O and Ni(ClO4)2·6H2O with disodium malonate and 1,10-phenanthroline in MeOH/H2O solution. Their crystal structures have been determined by X-ray diffraction. The structures of Complexes 1 and 2 show that each metal ion is coordinated by one 1,10-phenanthroline, two water molecules and a malonate ligand forming a distorted octahedral environment and each mononuclear fragment forms a 2D supramolecular network through H-bonding interactions. |
