Abstract

The title compound, C27H19BrN4O, is a mono-anil Schiff base ligand. Three intramolecular O-H center dot center dot center dot N and N-H center dot center dot center dot N hydrogen bonds involving the hydroxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak intermolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds together with pi-pi interactions [centroid centroid distances = 3.628 (3)-3.729 (3) angstrom] link neighboring molecules.
