M. Odoko, Y. Muranishi and N. Okabe

Abstract: The title compound, [Ni(C10H6NO2)2(H2O)2]·2H2O·2C2H5OH, contains a six-coordinate NiII ion displaying distorted octahedral coordination geometry defined by the two quinoline N atoms, two O atoms of the carboxylate groups and two O atoms of the water molecules. All of the corresponding pairs of ligand atoms lie in trans positions with respect to each other, the Ni atom lying on an inversion center. Molecules are linked together by an intermolecular hydrogen-bonding network involving the uncoordinated water and ethanol molecules.
