Abstract: In the title complex, [Co(C₇H₅O₃)(C₂₇H₂₇N₇)]ClO₄·1.5C₃H₇NO, the Co^II ion is five-coordinated by four N atoms from a tris(N-methylbenzimidazol-2-ylmethyl)amine (Mentb) ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry with approximate molecular C₃ symmetry. The perchlorate ion is disordered over two sites with equal occupancy. One dimethylformamide solvent molecule lies on a general position and is disordered over two coplanar orientations with equal occupancy. A second dimethylformamide molecule is disordered about a twofold rotation axis. There is an intramolecular O-HO hydrogen bond in the cation.
