Abstract

In the title compound, C13H13N3O, the NNCO unit forms dihedral angles of 35.8 (1) and 84.0 (1)° with the benzene and phenyl rings, respectively. The dihedral angles between the aromatic rings is 61.2 (1)°. An intra­molecular N—H⋯O hydrogen bond occurs. In the crystal, mol­ecules are linked by weak N—H⋯O hydrogen bonds into C(4) chains parallel to the c axis. Neighbouring chains are linked by weak N—H⋯N hydrogen bonds, forming R44(20) rings, and resulting in the formation of a two-dimensional network lying parallel to (010). The packing also features π–π stacking inter­actions between phenyl rings [centroid–centroid distance = 3.803 (2) Å].
