Abstract

The title compound, C(27)H(19)BrN(4)O, is a mono-anil Schiff base ligand. Three intra-molecular O-H⋯N and N-H⋯N hydrogen bonds involving the hydr-oxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak inter-molecular N-H⋯O and C-H⋯O hydrogen bonds together with π-π inter-actions [centroid-centroid distances = 3.628 (3)-3.729 (3) Å] link neighboring mol-ecules.
