摘要

The title compound, [Zn4(C28H18N4O2)2(CH3O)2](ClO4)2·2C3H7NO, is a C2 symmetric tetra­nuclear zinc(II) complex comprised of two [Zn2 L]²⁺ units bridged by a pair of μ2-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 Zn4(μ-OMe)2 unit lies in the cleft formed by two distinctly bent Schiff base ligands. The observed mol­ecular shape is supported by an intra­molecular π–π inter­action between one of the phenolate rings on each of the two ligands [centroid–centroid distance = 3.491 (5) Å]. The methyl groups of the solvent molecule are disordered over two sets of sites in a 0.6:0.4 ratio.
