Abstract

In the mol-ecule of the title compound, C(16)H(16)N(4)O, the pyrazole ring makes dihedral angles of 8.52 (13) and 9.26 (12)° with the phenyl rings. The dihedral angle between the benzene rings is 1.86 (13)°. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯N hydrogen bonds. Weak N-H⋯N inter-actions connect the dimers into a chain along the [100] direction. The pyrazole ring adopts a highly flattened envelope conformation.
