Özet

The title compound, C15H14N4O, crystallizes with two molecules in the asymmetric unit with similar conformations (r.m.s. overlay fit for the 20 non-H atoms = 0.175 angstrom). 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)degrees, respectively, with corresponding angles of 54.49 (7) and 49.61 (9) degrees, respectively, in the second molecule. In the crystal, the two molecules, together with their inversion-symmetry counterparts, are linked into tetramers by O - H center dot center dot center dot N hydrogen bonds. The tetramers form layers parallel to (211) through pairwise C - H center dot center dot center dot N interactions.
