Abstract: In the title compound, [Ni(C₇H₃NO₄)(C₆H₁₆N₂)(H₂O)]·2.5H₂O, the discrete neutral [Ni(dpc)(dien)(H₂O)] (dien is diethylethylenediamine and dpc is dipicolinate) complex lies on a mirror plane. The Ni^II ion is coordinated by the dpc ligand through the pyridine N atom and one O atom of each carboxylate group, an aqua ligand and two N atoms of the bidentate dien ligand, forming a distorted octahedral geometry. One of the C atoms of the ethylenediamine group is disordered across the mirror plane. The symmetry-independent ethyl group is disordered over two orientations with equal occupancy. The complex molecules are connected via O-HO and N-HO intermolecular hydrogen-bonding interactions.
