Abstract

The asymmetric unit of the title compound, C18H16N2O2, contains two independent molecules (A and B). In molecule A, the pyrazole ring is inclined at angles of 48.86 (6) and 60.80 (6)' with respect to the two phenyl rings; the corresponding angles for molecule B are 46.86 (6) and 58.63 (6)'. In the crystal, molecules of type A are linked into sheets parallel to (001) via weak C—H...O hydrogen bonds, whereas the molecules of type B are linked into chains along [010] via weak C—H...O hydrogen bonds.
