In the title compound, C27H21FN2O4, the mean planes of the indole ring systems (r.m.s. deviations = 0.0263 and 0.0160 Å) are approximately perpendic­ular to one another, making a dihedral angle of 84.0 (5)°; the fluoro­benzene ring is twisted with respect to the mean planes of the two indole ring systems at 89.5 (5) and 84.6 (3)°. In the crystal, pairs of N—H⋯O hydrogen bonds link the mol­ecules into inversion dimers, which are further linked by N—H⋯O hydrogen bonds into supra­molecular chains propagated along the b-axis direction. Weak C—H⋯π inter­actions are observed between neighbouring chains.

1. Chemical context

Bis(indol­yl)methane derivatives have been found widely in various terrestrial and marine natural resources (Porter et al., 1977[Porter, J. K., Bacon, C. W., Robbins, J. D., Himmelsbach, D. S. & Higman, H. C. (1977). J. Agric. Food Chem. 25, 88-93.]; Sundberg, 1996[Sundberg, R. J. (1996). The Chemistry of Indoles, p. 113. New York: Academic Press.]), and have many applications in pharmaceuticals with diverse activities, such as anti­cancer, anti­leishmanial and anti­hyperlipidemic (Chang et al., 1999[Chang, Y.-C., Riby, J., Chang, G. H.-F., Peng, B., Firestone, G. & Bjeldanes, L. F. (1999). Biochem. Pharmacol. 58, 825-834.]; Ge et al., 1999[Ge, X., Fares, F. A. & Yannai, S. (1999). Anticancer Res. 19, 3199-3203.]). Other, bis­(indoly)methane derivatives can also be used as a precursor for MRI contrast agents (Ni, 2008[Ni, Y.-C. (2008). Curr. Med. Imaging Rev. 4, 96-112.]). In recent years, we have reported the synthesis and crystal structures of some similar compounds (Sun et al., 2012[Sun, H.-S., Li, Y.-L., Xu, N., Xu, H. & Zhang, J.-D. (2012). Acta Cryst. E68, o2764.], 2013[Sun, H.-S., Li, Y.-L., Xu, N., Xu, H. & Zhang, J.-D. (2013). Acta Cryst. E69, o1516.], 2014[Sun, H.-S., Li, Y.-L., Jiang, H., Xu, N. & Xu, H. (2014). Acta Cryst. E70, 370-372.]; Li et al., 2014[Li, Y., Sun, H., Jiang, H., Xu, N. & Xu, H. (2014). Acta Cryst. E70, 259-261.]; Lu et al., 2014[Lu, X.-H., Sun, H.-S. & Hu, J. (2014). Acta Cryst. E70, 593-595.]). Now we report herein another bis­(indoly)methane compound.

2. Structural commentary

The mol­ecular structure of the title compound is shown in Fig. 1[link]. The two indole ring systems are approximately planar, the maximum deviations being 0.049 (3) and 0.030 (2) Å; the mean planes of the two indole ring systems nearly perpen­dicular to each other [dihedral angle = 84.0 (5)°] while the benzene ring (C22–C27) is twisted to the N1/C2–C9 and N2/C12–C19 indole ring systems by dihedral angles of 89.5 (5) and 84.6 (3)°, respectively. The carboxyl groups are approximately co-planar with the attached indole ring systems, the dihedral angles between the carboxyl groups and the mean planes of attached indole ring systems are 10.8 (3) and 12.3 (4)°.

3. Supra­molecular features

In the crystal, pairs of N1—H1A⋯O4i [symmetry code: (i) x, y + 1, z] hydrogen bonds link the mol­ecules into inversion dimmers, which are further linked by N2—H2A⋯O2ii [symmetry code: (ii) 1 − x, 1 − y, 1 − z] hydrogen bonds into supra­molecular chains propagated along the b axis (Table 1[link] and Fig. 2[link]). Weak C—H⋯π inter­actions are also observed between neighbouring chains.

E69, o1516.]), dimethyl 3,3′-[(4-chloro­phen­yl) methyl­ene]bis­(1H-indole-2-carboxyl­ate) (Li et al., 2014[Li, Y., Sun, H., Jiang, H., Xu, N. & Xu, H. (2014). Acta Cryst. E70, 259-261.]), dimethyl 3,3′-[(3-nitro­phen­yl) methyl­ene]bis­(1H-indole-2-carboxyl­ate) ethanol monosolvate (Sun et al., 2014[Sun, H.-S., Li, Y.-L., Jiang, H., Xu, N. & Xu, H. (2014). Acta Cryst. E70, 370-372.]) and dimethyl 3,3′-[(3-fluoro­phen­yl)methyl­ene]bis­(1H-indole-2-carboxyl­ate) (Lu et al., 2014[Lu, X.-H., Sun, H.-S. & Hu, J. (2014). Acta Cryst. E70, 593-595.]). In those structures, the two indole ring systems are also nearly perpendicular to each other, the dihedral angles being 82.0 (5), 84.5 (5), 79.5 (4), 89.3 (5) and 87.8 (5)°, respectively.

5. Synthesis and crystallization

Methyl indole-2-carboxyl­ate (17.5 g, 100 mmol) was dissolved in 200 ml methanol; commercially available 4-fluoro­benzaldehyde (6.2 g, 50 mmol) was added and the mixture was heated to reflux temperature. Concentrated HCl (3.7 ml) was added and the reaction was left for 1 h. After cooling the white product was filtered off and washed thoroughly with methanol. The reaction was monitored by TLC (CHCl3:hexane = 1:1). Yield was 90%. Single crystals of the title compound suitable for X-ray analysis were obtained by slow evaporation of a methanol solution. 1H NMR (300 MHz, DMSO) δ 11.81 (s, 2H), 7.59–7.36 (m, 3H), 7.13 (dd, J = 15.1, 7.2 Hz, 6H), 6.71 (t, J = 7.5 Hz, 2H), 6.60 (d, J = 8.3 Hz, 2H), 3.77 (s, 6H).

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. H atoms were positioned geometrically with N—H = 0.86 Å and C—H = 0.93–0.98 Å, and constrained to ride on their parent atoms. Uiso(H) = xUeq(C,N), where x = 1.5 for methyl H atoms and 1.2 for the others.

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.
