Abstract: In the title complex, [Zn(C₃H₃O₂)(C₂₇H₂₇N₇)](ClO₄)·C₃H₇NO·1.5CH₄O, the Zn^II ion is five-coordinated by four N atoms from a tris(1-methylbenzimidazol-2-ylmethyl)amine (Mentb) ligand and one O atom from an acrylate ligand in a distorted trigonal-bipyramidal geometry with approximate molecular C₃ symmetry. The atoms of the acrylate ligand are disordered over two sites, with approximate occupancies of 0.84 and 0.16. In addition, a methanol solvent molecule is disordered over two sites with equal occupancies. In the crystal structure, the full-occupancy methanol is linked to a dimethylformamide molecule by an intermolecular O-HO hydrogen bond.
