The oxadiazole ring makes dihedral angles of 13.90 (1) and 7.93 (1) with the naphthalene ring system and benzene ring, respectively, while the naphthalene ring system and benzene

The mean planes of the nitro groups in the anion are twisted from the phenyl ring mean plane with maximun angles of 24.7 (9)° and 3.9 (6)°, respectively.. The hydrogen atoms on

The carbazole ring system is almost orthogonal to phenyl ring (C19–C24) attached to sulfonyl group with dihedral angle of 87.51 (10)°.. The dihedral angle between the carbazole ring

and methyl-substituted quinoline benzene rings make a dihedral angle of 78.18 (4) and form dihedral angles of 45.91 (5) and 79.80 (4) , respectively, with the phenyl ring..

The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used

The pyridine ring is twisted with respect to the benzene ring and the naphthalene ring system, making dihedral angles of 41.9 (1) and 45.2 (1) , respectively.. In the

The plane containing the HNCO atoms subtends dihedral angles of 12.3 (4) and 8.1 (3) with the planes of the phenyl ring and benzothiazole group, respectively, whereas the

The thiazepine ring in the title compound, (I), is fused with the benzo ring and has four substituents: phenyl in position 2, hydroxy in position 3, oxo in position 4 and acetate
