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


ABSTRACT: 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.
