Abstract: In the title complex, [Cu(C₇H₅O₃)(C₂₇H₂₇N₇)]ClO₄·2C₃H₇NO, the Cu^II ion is five-coordinated by four N atoms from the tris(1-methyl-1H-benzimidazol-2-ylmethyl)amine ligand and an O atom of the monodentate salicylate ligand. The N₄O donor set defines a coordination geometry intermediate between square-pyramidal and trigonal-bipyramidal. The crystal structure is stabilized by O-HO interactions. The atoms of the aromatic ring of the salicylate ligand are disordered over two sites of equal occupancy. In addition, one of the dimethylformamide solvent molecules is partially disordered over two positions, of approximately equal occupancy.
