{4,4'-dimethyl-2,2'-[(2,2-dimethylpropane-1,3-diyl) bis(nitrilomethanylylidene)]diphenolato}nickel(II) monohydrate

Abstract

In the title compound, [Ni(C 21H 24N 2O 2)]·H 2O, both the complex molecule and the water molecule lie on a twofold rotation axis. The Ni II ion is coordinated in a distorted squareplanar geometry by the tetradentate ligand. The dihedral angle between the two symmetry-related benzene rings is 47.12(8)°. In the crystal, pairs of symmetry-related O-H ··· O hydrogen bonds form R 22(6) ring motifs. In addition, there are weak intermolecular C-H ··· O hydrogen bonds, and π-π stacking interactions with a centroid-centroid distance of 3.4760(8) Å.
