In the title complex, [Zn(C18H10N4O2)(CH4O)], the Zn(2+) cation is located on a mirror plane and is coordinated by a tetradentate Schiff base ligand anion (L (2-)) and a methanol mol-ecule. The Zn(2+) cation is surrounded by two N atoms and two O atoms from L (2-), in a nearly planar configuration, and one methanol O atom, forming a slightly distorted square-pyramidal geometry. The methanol molecule is disordered over two sets of sites in a 0.5:0.5 ratio. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into chains parallel to [001].
