Abstract
In the crystal structure of the title compound, C30H24N4O2S, the dihydroquinoxaline 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)degrees with respect to the pyrazole ring. The rings of the phenyl and tolyl substituents are aligned at 64.0 (1) and 43.7 (1)degrees with respect to the pyrazole ring. Weak intermolecular C-H center dot center dot center dot O hydrogen bonding links the molecules, forming supramolecular chains running along the a axis.
