(Received 15 December 2010; accepted 21 December 2010; online 8 January 2011)

There are two independent molecules in the asymmetric unit of the title compound, C25H24F2N6, in which the N=N bonds adopt a trans configuration with distances in the range 1.262 (2)–1.269 (3) Å. The dihedral angles between heterocycles are 86.7 (2) and 85.6 (2)° in the two molecules while the dihedral angles between the heterocylic rings and the adjacent benzene rings are 13.4 (2) and 13.4 (2)° in one molecule and 5.3 (2) and 6.5 (2)° in the other. In the crystal, pairs of independent mol­ecules are held together by four N—H⋯N hydrogen bonds, forming inter­locked dimers.

Comment top

In previous work, we reported the crystal structrues of chloro, bromo and iodo substituted 5,5'-bisphenyldiazo-dipyrromethane compounds (Yin et al. 2009). Herein, we report the crystal of 5,5'-bis(4-fluorophenyldiazo) -dipyrromethane (I). The molecular structrue of (I) is shown in Fig. 1. In the structrue, all the N N adopt trans conformantion and their distance is at the range of 1.262 (2)Å to 1.269 (3) Å, which is shorter than that of its analogues. Same to its analogues, two molecules of the title compound are held together by four N—H···N hydrogen bonds and consequently form an interlocked type dimer. However, in the crystal structrue of (I), no halogen···π interaction is observed. It indicates that the fluorine atom is a poor halogen bonding donor (Metrangolo et al. 2008).

Experimental top

A 0°C solution of the 4-fluoroaniline (5 mmol) and aqueous HCl (4 ml) in water 4 (ml) was treated with a 0°C solution of NaNO2 (0.35 g, 5 mmol) in water (10 ml), and the mixture was stirred at 0°C for 0.5 h. The diazonium salt solution was added drop wise to the solution of dipyrromethane (0.5 g, 2.5 mmol) in acetonitrile (25 ml) and three drops of acetic acid. The combined solution was maintained at 0°C for 2 h with stirring. After this time, EtOAc (25 ml) and water (25 ml) were added. The organic layer was separated and washed with water (20 ml) and dried with anhydrous MgSO4. The dried solution was evaporated and the residue was purified by column chromatography on silica.

Refinement top

N—H located from difference map and refined freely. Other H atoms were placed in difference Fourier map (C—H = 0.93 or 0.97 Å) and included in the final cycles of refinement using a riding model, with Uiso(H) = 1.2 Ueq(C).

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.
