Abstract
In the title complex, [Zn(C7H5O3)(C27H27N7)]ClO4·1.5C3H7NO, the ZnII atom is five-coordinated by four N atoms from a tris(N-methylbenzimidazol-2-ylmethyl)amine ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry (τ parameter = 0.84), with approximate molecular C 3 symmetry. One dimethylformamide 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.
