4,4′-Dimethoxy-2,2′-[2,2-dimethylpropane-1,3-diylbis(nitrilomethanylylidene)]diphenol

In the title compound, C19H18Cl4N2O2, a potential tetradentate Schiff base ligand, the dihedral angle between the two benzene rings is 48.01 (10)°. The configuration about the two C=N bonds is E and two intramolecular O—H⋯N hydrogen bonds make S(6) ring motifs. In the crystal, molecules are linked along the b axis via intermolecular C—H⋯Cl interactions. The crystal structure is further stabilized by an intermolecular π–π interaction [centroid–centroid distance = 3.5744 (12) Å].

In the title compound, [Ni(C21H24N2O2)]·H2O, both the complex molecule and the water molecule lie on a twofold rotation axis. The NiII ion is coordinated in a distorted square-planar 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 2 2(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.
