Abstract: In the title compound, [Ni(C20H22N2O4)]·H2O, the NiII ion and the water molecule are located on a twofold rotation axis. The Ni ion is coordinated by two N [Ni-N = 1.8462 (18) Å] and two O [Ni-O = 1.8645 (14) Å] atoms in a distorted square-planar geometry. The water molecule and the Ni complex molecule are paired via O-HO hydrogen bonds.
