In the crystal of the dinuclear title compound, [Cu2(C13H13N2O)2(ClO4)2]·2CH3CN, the two bridging perchlorate ions chelate to the two CuII atoms in a μ-O:O′ fashion on opposite sides of the equatorial plane. The CuII ions display a distorted octa­hedral coordination geometry (in the usual 4 + 2 Jahn–Teller arrangement), each being coordinated by two O atoms from the two perchlorate ligands, and two N and O atoms from the reduced Schiff base ligand. The asymmetric unit contains two acetonitrile solvent mol­ecules. In the crystal structure, in addition to N—H⋯O hydrogen bonds, there are weak C—H⋯O inter­actions between the perchlorate O atoms and the reduced Schiff base ligand. C—H⋯N inter­actions are also present.
