The title compound, [Zn(4)(C(28)H(18)N(4)O(2))(2)(CH(3)O)(2)](ClO(4))(2)center dot 2C(3)H(7)NO, is a C2 symmetric tetranuclear zinc(II) complex comprised of two [Zn(2)L](2+) units bridged by a pair of mu(2)-OMe ligands (where L is the doubly-deprotonated form of the macrocyclic dinucleating ligand derived from the [2 + 2] Schiff base condensation between 2-hydroxybenzene-1,3-dicarbaldehyde and 1,2-diaminobenzene). Each Zn(II) atom has a distorted square-pyramidal coordination geometry and the Zn(4)(mu-OMe)(2) unit lies in the cleft formed by two distinctly bent Schiff base ligands. The observed molecular shape is supported by an intramolecular pi-pi interaction between one of the phenolate rings on each of the two ligands [centroid-centroid distance = 3.491 (5) angstrom]. The methyl groups of the solvent molecule are disordered over two sets of sites in a 0.6:0.4 ratio.
