Each compound contains a 1,2,4-triazole ring and two benzene rings, which are essentially planar. The molecules are linked by a combination of intermolecular NH...O and N-H...N hydrogen bonds. Additionally, there is a weak pi-pi stacking interaction in (I), involving the benzene ring of the aminobenzyl group and the partially aromatic 1,2,4-triazole moiety, with a centroid-centroid distance of 3.7397 (10) Angstrom.eninfo:eu-repo/semantics/closedAccessArticle61O101O10410.1107/S01082701040339312-s2.0-3094445825615695905N/AWOS:000227376600038N/A
