RESUMO
In the mol-ecule of the title compound, C(19)H(19)N(3)O(2), the central pyrazole ring makes dihedral angles of 9.89â (3) and 66.06â (5)° with the two phenyl rings, and the two phenyl rings form an angle of 74.05â (5)°. An intra-molecular C-Hâ¯O hydrogen bond forms a six-membered ring, producing an S(6) ring motif. In the crystal structure, inter-molecular N-Hâ¯O and C-Hâ¯O hydrogen bonds link each mol-ecule to two others, forming an infinite one-dimensional supra-molecular structure along the c axis.
