Abstract top

The title compound, C25H14Cl2N4, crystallizes with two independent molecules in the asymmetric unit. The two pyridine rings are almost coplanar, making dihedral angles of 3.2 (1) and 8.6 (1)° in the two independent molecules. The dichlorophenyl and indole rings are twisted away from the bipyridine ring by 64.32 (5) and 18.46 (4)°, respectively in the first molecule and by 51.0 (1) and 27.99 (5)°, respectively in the second molecule. The crystal packing is stabilized by C-H...N, C-H...Cl, N-H...N and C-H...[pi] interactions.

Comment top

Pyridine derivatives containing multi-functional groups can be used as drugs such as streptonigrin, streptonigrone and lavendamycin which are reported as anticancer drugs, and itavastatin, cerivastatin are reported as the HMG-CoA enzyme inhibitors (Zhou et al., 2008). Indole derivatives are used as bioactive drugs (Stevenson et al., 2000) and they exhibit anti-allergic, central nervous system depressant and muscle relaxant properties (Harris & Uhle 1960; Ho et al., 1986). Indoles have been proved to display high aldose reductase inhibitory activity (Rajeswaran et al., 1999).

The ORTEP diagram of the title compound is shown in Fig. 1. In the title compound, there are two crystallographically independent molecules in the asymmetric unit. The two pyridine rings lie in the same plane as can be seen from the dihedral angle of 3.2 (1)° and 8.6 (1)°. The dichlorophenyl and indole rings are twisted away from the bipyridine ring by 64.32 (5)° and 18.46 (4)°, respectively. In the benzene ring of the indole ring system, the endocyclic angels at C12 and C12' are contracted to 117.7 (2)° and 117.9 (3)°, while those at C13 and C13' are expanded to 123.0 (2)° and 122.2 (3)°, respectively. This would appear to be a real effect caused by the fusion of the pyrrole with benzene ring resulting in an angular distortion. The sum of the bond angles around N14(359.3)° and N14'(360.3)° are in accordance with sp2 hybridization. The bond angles of C3—C16—N17 (178.0 (3))° and C3'-C16'-N17' (178.0 (3))° show the linearity of the cyano group, a feature observed in carbonitrile compounds.

The crystal packing is controlled by C—H···N, C—H···Cl, N—H···N and C—H···π types of intra and intermolecular interactions in addition to van der Waals forces. Atoms N14 and N14' at (x, y, z) donate one proton each to N17 (-x, y + 1/2, -z + 1/2) and N17'(-x, y - 1/2, -z + 1/2) which connects the molecules to form a dimer with a graph-set-motiff R22(16) (Bernstein et al., 1995). These dimers are linked into a zigzag chain running along b axis through intermolecular C5—H5···Cl2' hydrogen bond which is shown in Fig. 2.

Experimental top

A mixture of 4-(2,4-dichlorophenyl)-6-(1H-indol-3-yl)-1,4-dihydro -2,2'-bipyridine-5-carbonitrile (1 mmol) and urea oxalate (20 mol%) was irradiated in a microwave oven in ethanol for 5 min. After the completion of the reaction (as monitored by TLC), it was poured into water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated under vacuo. The crude product was chromatographed and isolated in 86% yield (90:10, petroleum ether: ethyl acetate). The compound was recrystallized in ethanol.

Refinement top

H atoms bonded to nitrogen were freely refined; those bonded to carbon were positioned geometrically (C—H=0.93 Å) and allowed to ride on their parent atoms, with 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.
