Abstract: In the title complex, [Cu(C₄H₅O₂)(C₂₇H₂₇N₇)](ClO₄)·2C₃H₇NO·0.5H₂O, the Cu^II ion is five-coordinated by four N atoms from a tris(N-methylbenzimidazol-2-ylmethyl)amine ligand and one O atom from a 2-methacrylate ligand in a distorted trigonal-bipyramidal geometry with approximate molecular C₃ symmetry. A half-occupancy solvent water molecule forms weak O-HO hydrogen bonds and the atoms of the 2-methacrylate ligand are disordered over two sites with equal occupancy.
