Crystal structure of (E)-N-{[3-methyl-1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]methyl­idene}hydroxyl­amine

The title compound, C(15)H(14)N(4)O, crystallizes with two mol­ecules in the asymmetric unit with similar conformations (r.m.s. overlay fit for the 20 non-H atoms = 0.175 Å). In the first mol­ecule, the dihedral angles between the planes of the central pyrazole ring and the pendant phenyl and pyrrole rings are 42.69 (8) and 51.88 (6)°, respectively, with corresponding angles of 54.49 (7) and 49.61 (9)°, respectively, in the second mol­ecule. In the crystal, the two mol­ecules, together with their inversion-symmetry counterparts, are linked into tetra­mers by O—H⋯N hydrogen bonds. The tetra­mers form layers parallel to (211) through pairwise C—H⋯π inter­actions.
