Abstract
The title compound crystallizes in the orthorhombic space group Pbca with a = 8.283(1), b = 26.201(2), c = 14.066(2)A, V = 3052.8(5)A3, Z = 8, Dcal = 1.368 Mg/m3. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data and refined by full-matrix least-squares procedures to a final R-value of 0.0356 for 2536 observed reflections. The pyrazoline ring is in an envelope conformation. The dihedral angles between the pyrazoline ring and the phenyl rings A and B are 68.2(1) and 12.1(1)°, respectively. The crystal packing is influenced by O-H…N, N-H…O, C-H…O, C-H…π hydrogen bonds, and π-π interactions.
