4-(3-Phenyl-3,3a,4,5-tetrahydro-2H-benzo[g]indazol-2-yl)benzenesulfonamide ethanol monosolvate

Abstract: In the title compound ethanol monosolvate, C23H21N3O2S·C2H5OH, the dihydro­pyrazole ring is twisted about the Csp 3—Csp 3 bond. Nevertheless, the ring approximates a plane (r.m.s. deviation for the fitted atoms = 0.132 Å) and forms dihedral angles of 5.80 (13) and 12.29 (12)°, respectively, with the fused- and sulfonamide-benzene rings. As the dihydro­pyrazole C-bound phenyl group is roughly perpendicular to the dihydro­pyrazole ring [dihedral angle = 74.04 (15)°; the amino group is orientated to the same side… Show more

“…In the 3-chloro-2,2-dimethylpropanamide moiety of (I), the N2-C7-C8-C9, N2-C7-C8-C10 and N2-C7-C8-C11 torsion angles are 178.6 (4), 57.2 (5) and -59.4 (5) °, respectively. The values of the bond lengths and bond angles in (I) are within the normal range and are comparable to those previously reported for the related structures (Akkurt et al, 2010;Idemudia et al, 2012;Asiri et al, 2012). The crystal structure is stabilized by intermolecular N-H···O and C-H···O hydrogen bonds (Table 1 and Fig.…”
