The asymmetric unit of the title compound, C19H15N, contains two crystallographically independent mol­ecules. In both mol­ecules, the planar carbazole moieties [maximum deviations = 0.037 (4) and 0.042 (3) Å] are oriented with respect to the adjacent benzene rings, at dihedral angles of 85.29 (8) and 89.89 (7)°, respectively. In the crystal structure, weak C—H⋯π inter­actions are observed involving the carbazole rings.

Comment top

Tetrahydrocarbazole systems are present in the framework of a number of indole-type alkaloids of biological interest (Phillipson & Zenk, 1980; Saxton, 1983; Abraham, 1975). The structures of tricyclic, tetracyclic and pentacyclic ring systems with dithiolane and other substituents of the tetrahydrocarbazole core, have been the subject of much interest in our laboratory. These include 1,2,3,4-tetrahydrocarbazole-1-spiro-2'-[1,3]dithiolane, (II) (Hökelek et al., 1994), N-(2-methoxyethyl)-N-{2,3,4,9-tetrahydrospiro[1H-carbazole-1, 2-(1,3)dithiolane]-4-yl}benzene-sulfonamide, (III) (Patır et al., 1997), spiro[carbazole-1(2H),2'-[1,3]-dithiolan]-4(3H)-one, (IV) (Hökelek et al., 1998), 9-acetonyl-3-ethylidene-1,2,3,4-tetrahydrospiro[carbazole-1,2'-[1,3] dithiolan]-4-one, (V) (Hökelek et al., 1999), N-(2,2-dimethoxyethyl)-N -{9-methoxymethyl-1,2,3,4-tetrahydrospiro[carbazole-1,2'-[1,3]dithiolan] -4-yl}benzamide, (VI) (Hökelek & Patır, 1999), 3a,4,10,10 b-tetrahydro-2H -furo[2,3-a]carbazol-5(3H)-one, (VII) (Çaylak et al., 2007); also the pentacyclic compounds 6-ethyl-4-(2-methoxyethyl)-2,6-methano-5-oxo-hexahydro- pyrrolo(2,3-d)carbazole-1-spiro-2'-(1,3)dithiolane, (VIII) (Hökelek & Patır, 2002), N-(2-benzyloxyethyl)-4,7-dimethyl-6-(1,3-dithiolan-2-yl)-1,2, 3,4,5,6-hexahydro-1,5-methano-2-azocino[4,3-b]indol-2-one, (IX) (Hökelek et al., 2004) and 4-ethyl-6,6-ethylenedithio-2-(2-methoxyethyl)-7-methoxy- methylene-2,3,4,5,6,7-hexahydro-1,5-methano-1H-azocino[4,3-b]indol-3-one, (X) (Hökelek et al., 2006). The title compound, (I), may be considered as a synthetic precursor of tetracyclic indole alkaloids of biological interests. The present study was undertaken to ascertain its crystal structure.

The title compound consists of a carbazole skeleton with a benzyl group. Its asymmetric unit, (Fig. 1), contains two crystallographically independent molecules, where the bond lengths (Allen et al., 1987) and angles are within normal ranges, and generally agree with those in compounds (II)-(X). In all structures atom N9 is substituted.

An examination of the deviations from the least-squares planes through individual rings shows that rings A (C1—C4/C4a/C9a), B (C4a/C5a/C8a/N9/C9a), C (C5a/C5—C8/C8a), D (C11—C16) and A' (C1'-C4'/C4a'/C9a'), B' (C4a'/C5a'/ C8a'/N9'/C9a'), C' (C5a'/C5'-C8'/C8a'), D' (C11'-C16') are planar. The carbazole skeletons, containing the rings A, B, C and A', B', C' are also nearly coplanar [with a maximum deviations of 0.037 (4) and 0.042 (3) Å for atoms C2 and C7', respectively] with dihedral angles of A/B = 1.28 (10), A/C = 1.57 (9), B/C = 0.32 (7) ° and A'/B' = 0.94 (10), A'/C' = 2.37 (10), B'/C' = 1.72 (11) °. Rings D and D' are oriented with respect to the planar carbazole skeletons at dihedral angles of 85.29 (8) and 89.89 (7) °, respectively. Atoms C10 and C10' displaced by -0.109 (3), -0.005 (4) Å and -0.016 (3), -0.098 (3) Å from the planes of the corresponding carbazole skeletons and benzene rings, respectively.

In the crystal structure, three weak C—H···π interactions (Table 1) involving the carbazole rings are observed.

Experimental top

For the preparation of the title compound, (I), sodium hydride (2.38 g, 59.85 mmol) was added to a solution of carbazole (5.00 g, 29.92 mmol) in dry tetrahydrofuran (200 ml) in several portions, and stirred at room temperature for 1 h under argon atmosphere. Then, benzylchloride (5.68 g, 44.88 mmol) was added and stirred at 343 K for 6 h. The reaction mixture was cooled in an ice bath, and hydrochloric acid (10%, 200 ml) was added. After the extraction with dichloromethane (300 ml), the organic layer was dried over anhydrous magnesium sulfate and the solvent was evaporated under reduced pressure. The residue was purified by column chromatograpy using silica gel and dichloromethane-petroleum ether (1:1), and the product was recrystallized from diethyl ether and cyclohexane mixture (1:1) (yield; 4.00 g, 80%, m.p. 388 K).

Refinement top

H3 and H7' atoms were positioned geometrically, with C—H = 0.93 Å for aromatic H atoms and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C). The remaining H atoms were located in difference synthesis and refined isotropically.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. 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 when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
