title: μ-Acetato-μ-(5-chloro-2-{1,3-bis[2-(5-chloro-2-oxidobenzylideneamino)ethyl]imidazolidin-2-yl}phenolato)-bis[methanolnickel(II)] methanol monosolvate monohydrate.
abstract: The crystal structure shows that the title compound, [Ni(2)(CH(3)CO(2))(C(27)H(24)Cl(3)N(4)O(3))(CH(4)O)(2)]·CH(3)OH·H(2)O, con-tains [Ni(2)L(OAc)(CH(3)OH)(2)] mol-ecules in the unit cell {H(3)L = 5-chloro-2-{1,3-bis[2-(5-chloro-2-oxidobenzylideneimino)-ethyl]imidazolidin-2-yl}phenolate} with water and methanol as solvates. The title compound is a neutral dinuclear compound, in which the L(3-) Schiff base acts as a hepta-dentate ligand, using each one of its N(2)O compartments to coordinate a nickel atom. The acetate anion bridges the two nickel atoms via one O while the distorted octahedral coordination sphere for each nickel atom is completed by a coordinated methanol ligand. One of the coordinated methanol ligands is involved in an intra-molecular hydrogen bond to the uncoordinated O atom of the bridging acetate ligand while the other forms a hydrogen bond with the methanol solvate. The solvate water mol-ecule forms strong hydrogen bonds to both terminal phenolato O atoms. The methanol solvate mol-ecule also forms a hydrogen bond with the water solvate mol-ecule.
