(4,9 Di­methyl 9H carbazol 3 yl)meth­anol

There is an intramolecular N—H N hydrogen bond involving the amino group (N3—H3) in the carbazole ring and an imine N atom (N2), generating an S (6) ring motif (Table 1)..

Bond lengths and angles in both ring systems are normal and similar to those found in the numerous other carbazole structures (see, for example, Kimura et al. , 1985) and those of

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

In this hydroxyl derivative the molecule is more planar, with a dihedral angle of 11.58 (12)° between the planes of the carbazole ring system and benzene ring.. Also in the

Carbazole derivatives substituted by N -alkylation possess valuable pharmaceutical properties (Buu-Hoï & Royer, 1950; Harfenist & Joyner, 1983; Caulfield et al.. In

(Bruker, 2004); data reduction: SAINT ; program(s) used to solve structure: SHELXS97 (Sheldrick, 2008); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008);

The molecular back- bone is nearly planar, as indicated by the dihedral angle of 11.58 (12) between the planes of the carbazole and

The biological activity of compounds with benzothiazole skeletons includes anticancer, antibacterial, antifungal and anthelmintic properties (Aiello et al., 2008; Cho et al.,
