A nickel(II) complex of an unsymmetrical tetradentate Schiff base

The structure of the title nickel(II) complex, (2-{2-[α-(5-chloro-2-oxido­phenyl)­benzyl­idene­amino]­phenyl­imino­methyl}-5-hydroxy­phenolato)­nickel(II) methanol disolvate, [Ni(C₂₆H₁₇ClN₂O₃)]·2CH₃OH, containing an unsymmetrical tetradentate schiff base, comprises two neutral [Ni(CBP-PHEN-4-OHSAL)] complex mol­ecules and four methanol solvent mol­ecules in the asymmetric unit. Each Ni^II center exists in a four-coordinate square-planar geometry defined by an N₂O₂ donor set.
