{6,6'-Dieth-oxy-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}nickel(II) monohydrate.

ABSTRACT: In the title complex, [Ni(C(23)H(28)N(2)O(4))]·H(2)O, the Ni(II) ion is coordinated by the N(2)O(2) unit of the tetra-dentate Schiff base ligand in a slightly distorted planar geometry. The asymmetric unit of the title compound comprises one complex mol-ecule and a water mol-ecule of crystallization. The H atoms of the water mol-ecule make bifurcated inter-molecular hydrogen bonds with the O atoms of the phenolate and eth-oxy groups with R(1) (2)(5) and R(1) (2)(6) ring motifs, which may, in part, influence the mol-ecular configuration. The dihedral angle between the two benzene rings is 31.43 (5)°. The crystal structure is further stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions, which link neighbouring mol-ecules into one-dimensional extended chains along the a axis. An inter-esting feature of the crystal structure is the short inter-molecular C⋯C [3.3044 (14) Å] contact which is shorter than the sum of the van der Waals radii.
