The crystal structure shows that the title compound, [Ni-2(CH3CO2)(C27H24Cl3N4O3)(CH4O)(2)]center dot CH3OH center dot H2O, contains [Ni2L(OAc)(CH3OH)(2)] molecules in the unit cell {H3L = 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 L3- Schiff base acts as a heptadentate ligand, using each one of its N2O 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 intramolecular 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 molecule forms strong hydrogen bonds to both terminal phenolato O atoms. The methanol solvate molecule also forms a hydrogen bond with the water solvate molecule.
