Abstract:
The asymmetric unit of the title compound, C15H15N3O2, comprises two crystallographically independent molecules (A and B), each having an E conformation around the C=N bond. In each molecule, there is an intramolecular O—H⋯N hydrogen bond making an S(6) ring motif. The dihedral angles between the substituted phenyl rings are 17.49 (9) and 10.03 (9)°. In the crystal, N—H⋯O hydrogen bonds link neighbouring independent molecules into infinite chains, of the type –A–B–A–B–, along the a axis, enclosing R21(7) ring motifs. The chains are linked by N—H⋯O hydrogen bonds and C—H⋯O interactions, leading to the formation of a three-dimensional network.
