2-[(E)-(5-Amino-2,3-diphenylquinoxalin-6-yl)iminomethyl]-4-chlorophenol

Abstract

The title Schiff base compound, C27H19ClN4O, features two intramolecular O—H...N and N—H...N hydrogen bonds involving the hydroxy and amino groups to generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak intermolecular N—H...O and C—H...N interactions, together with π–π contacts [centroid–centroid distances = 3.6294 (11)–3.6881 (11) Å], link neighboring molecules.
