3-Acetyl-5-methyl-1-(4-methyl-phen-yl)-1H-pyrazole-4-carboxamide. 2010

Hatem A Abdel-Aziz, and Ahmed Bari, and Seik Weng Ng

In the title compound, C(14)H(15)N(3)O(2), the phenyl-ene ring is disordered over two orientations. As a result, the almost planar pyrazole ring (r.m.s. deviation = 0.004 Å) forms dihedral angles of 59.8 (1) and -61.9 (1)° with the two orientations of the phenyl-ene ring. The dihedral angle between the two orientations is 59.2 (1)°. In the crystal, inversion dimers lined by pairs of N-H⋯O hydrogen bonds occur; there is also an intramolecular N-H⋯O bond.
