3-(5-Phenyl-4-phenyl-sulfonyl-1-p-tolyl-1H-pyrazol-3-yl)-1,2-dihydro-quinoxaline.

In the crystal structure of the title compound, C(30)H(24)N(4)O(2)S, the dihydro-quinoxaline fused-ring system is disordered over three orientations in a 0.358 (2):0.318 (3):0.324 (3) ratio; the mean planes of the non-H atoms of the disorder components are aligned at 4.0 (3), 11.8 (4) and 41.7 (2)° with respect to the pyrazole ring. The rings of the phenyl and tolyl substituents are aligned at 64.0 (1) and 43.7 (1)° with respect to the pyrazole ring. Weak intermolecular C-H⋯O hydrogen bonding links the mol-ecules, forming supra-molecular chains running along the a axis.
