Abstract
In the title compound, C20H21N5O, the dihedral angles between the central phenol ring and pendant toluyl and imidazole rings are 3.20 (16) and 81.44 (14)°, respectively; the dihedral angle between the pendant rings is 84.39 (16)°. An intramolecular O—H...N hydrogen bond occurs. A Hirshfeld fingerprint analysis indicates that H...H contacts account for 48.6% of the surface.

Summary
As a continuation of our studies of compounds based on azo Schiff base derivatives (Slassi et al, 2017), we report the synthesis and structure of the title compound. The bond lengths and angles of the imidazol moiety are comparable with those reported for similar compounds (Slassi et al, 2017). An intramolecular O—HÁ Á ÁN hydrogen bond occurs (Table 1) but no directional interactions beyond van der Waals’ contacts could be identified in the packing (Fig. 2). Two-dimensional Hirshfeld fingerprint plots (McKinnon et al, 2007) indicate that 48.6% of the surface is due to HÁ Á ÁH contacts, followed by CÁ Á ÁH, NÁ Á ÁH and OÁ Á ÁH interactions, which contribute 28.5, 15.2 and 6.1%, respectively
