μ-Acetato-aqua-μ-(5-bromo-2-{1,3-bis­[2-(5-bromo-2-oxidobenzyl­idene­amino)­eth­yl]imidazolidin-2-yl}phenolato)methano­ldinickel(II) methanol disolvate monohydrate

The crystal structure of the title compound, [Ni(2)(C(27)H(24)Br(3)N(4)O(3))(CH(3)CO(2))(CH(3)OH)(H(2)O)]·2CH(3)OH·H(2)O contains [L(OAc){(CH(3)OH)Ni}{(H(2)O)Ni}] mol­ecules {H(3) L = 2-(5-bromo-2-hy­droxy­phen­yl)-1,3-bis­[4-(5-bromo-2-hy­droxy­phen­yl)-3-aza­but-3-en­yl]-1,3-imidazolidine} with additional water and two methanol solvent mol­ecules. In this instance, one of the two Ni atoms is coordinated to a water and the other to a methanol mol­ecule. The Ni—O and Ni—N distances, as well as the angles about the metal atoms, show quite regular octa­hedra around the central ions. The Ni—O(phenol)—Ni and Ni—O(acetate)—Ni angles are not similar [95.26 (13) and 97.34 (13)°, respectively], indicating that this subtle solvate exchange induces significant differences in the conformation adopted. The coordinated methanol ligand is involved in an intra­molecular hydrogen bond to the uncoordinated O atom of the bridging acetate ligand, while the coordinated water mol­ecule forms a hydrogen bond with the one of the methanol solvent mol­ecules. The water solvent mol­ecule forms strong hydrogen bonds to both phenolate O atoms. The remaining methanol solvent mol­ecule also forms a hydrogen bond with this solvent water mol­ecule.
