Abstract
In the title mononuclear complex, [Zn(C21H16N3O)Cl], the Zn-II ion is coordinated in a distorted tetrahedral geometry by two benzimidazole N atoms and one phenolate O atom from the tridentate Schiff base ligand and a chloride ligand. The benzimidazole ring system forms dihedral angles of 26.68 (9) and 56.16 (9)degrees with the adjacent benzene ring and the methylphenolate group benzene ring, respectively. In the crystal, molecules are linked by N-H center dot center dot center dot Cl hydrogen bonds into chains along [100]. Furthermore, weak C-H center dot center dot center dot O and C-H center dot center dot center dot pi nteractions, in addition to pi-pi interactions with centroid-centroid distances in the range 3.5826 (13)-3.9681 (13) angstrom, are also observed.
