The asymmetric unit of the title compound, C22H20N2, contains two crystallographically independent mol­ecules in which the planar benzimidazole ring systems are oriented with respect to the adjacent tolyl rings at dihedral angles of 47.08 (8)/76.85 (8) and 39.52 (9)/87.49 (9)°, while the dihedral angles between the tolyl rings are 73.99 (3) and 81.51 (9)°. In the crystal structure, pairs of inter­molecular C—H⋯N inter­actions link one of the asymmetric mol­ecules into centrosymmetric dimers through R22(8) ring motifs.

Comment top

Benzimidazole derivatives have attracted considerable attention because of their biological and pharmaceutical activities (Matsuno et al., 2000; Garuti et al., 1999). In addition, they play an important role in the development of coordination chemistry. Many derivatives of benzimidazole have been prepared and their complexes have been studied (Tlahuext et al., 2007; Chen & Ruan, 2007). We report herein the crystal structure of the title compound.

The asymmetric unit of the title compound contains two crystallographically independent molecules (Fig. 1), in which the bond lengths (Allen et al., 1987) and angles are within normal ranges. Rings A (C1-C6), B (N1/N2/C8/C9/C14), C (C9-C14), D (C16-C21) and E (C23-C28), F (N3/N4/C30/C31/C36), G (C31-C36), H (C38-C43) are, of course, planar. The planar benzimidazole ring systems, (N1/N2/C8-C14) and (N3/N4/C30-C36), are oriented with respect to the adjacent rings, A, D and E, H, at dihedral angles of 47.08 (8), 76.85 (8) ° and 39.52 (9), 87.49 (9) °, respectively, while the dihedral angles between rings A, D and E, H are 73.99 (3) and 81.51 (9) °, respectively.

In the crystal structure, intermolecular C-H···N interactions (Table 1) link the molecules into centrosymmetric dimers through R22(8) ring motifs (Bernstein et al., 1995) (Fig. 2), in which they may be effective in the stabilization of the structure.

Experimental top

For the preparation of the title compound, 4-methylbenzaldehyde(0.96 g, 8 mmol) was added to a solution of o-phenylenediamine (0.432 g, 4 mmol) in ethanol (20 ml). The mixture was refluxed with stirring for 4 h. When cooled to room temperature, the resultant solution was filtered and allowed to evaporate slowly. Crystals suitable for X-ray analysis were obtained after several weeks.

Refinement top

H atoms were positioned geometrically, with C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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.
