Abstract (EN):
In the title compound, [Ni(C19H20N2O4)(H2O)(2)], the Ni atom has a distorted octahedral coordination geometry in which the tetradentate Schiff base ligand acts as a cis-N2O2 donor defining an equatorial plane, and water molecules occupy the axial positions. The two parts of the molecule are related by a mirror plane that passes through the Ni atom and is perpendicular to the equatorial plane. The angular distortions from normal octahedral geometry are in the range 1-6 degrees, and the equatorial plane, defined by the donor atoms of the Schiff base, is almost square planar. The six-membered ring comprising the Ni, the imine N and the propylene C atoms adopts a half-chair conformation. The Ni-O [2.017 (2) Angstrom] and Ni-N [2.071 (2) Angstrom] distances are within the ranges expected for high-spin octahedral nickel complexes.
