(2-Hydroxy­benzoato-κO (1))[tris­(1-methyl­benzimidazol-2-ylmethyl-κN (3))amine-κN]cobalt(II) perchlorate dimethyl­formamide sesquisolvate

In the title complex, [Co(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·1.5C(3)H(7)NO, 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 C (3) 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—H⋯O hydrogen bond in the cation.
