title: {4,4'-Dimethyl-2,2'-[(2,2-dimethyl-propane-1,3-di-yl)bis-(nitrilo-methanylyl-idene)]diphenolato}nickel(II) monohydrate.
abstract: In the title compound, [Ni(C(21)H(24)N(2)O(2))]·H(2)O, both the complex mol-ecule and the water mol-ecule lie on a twofold rotation axis. The Ni(II) ion is coordinated in a distorted square-planar geometry by the tetra-dentate 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(2) (2)(6) ring motifs. In addition, there are weak inter-molecular C-H⋯O hydrogen bonds, and π-π stacking inter-actions with a centroid-centroid distance of 3.4760 (8) Å.
