In the title compound, C28H19FN2O, the phenanthrene fused with an imidazole ring, constituting an essentially planar tetra­cyclic system [maximum deviation = 0.032 (2) Å], makes dihedral angles of 60.83 (4) and 80.55 (4)° with the fluoro­benzene and meth­oxy­benzene rings, respectively. The dihedral angle between the the meth­oxy­benzene and fluoro­benzene rings is 69.45 (6)°. In the crystal, C—H⋯O hydrogen bonds connect the mol­ecules into infinite strands along the b axis. The crystal structure is further consolidated by C—H⋯π inter­actions.

Comment top

1H-phenanthro[9,10-d]imidazole can be used as a planar synthetic building block in supramolecular chemistry (Krebs & Spanggaard, 2002). Its derivatives are commonly used as ligands in metal complexes (Bian et al., 2002). Some phenanthrene derivatives have excellent coordinating abilities and have been used to build supramolecular architechture (Che et al., 2008; Stephenson & Hardie, 2006). We have synthesized the title compound in our laboratory and determined its crystal structure which is reported in this article.

The bond lengths and bond angles in the title compound (Fig. 1) are normal and agree very well with the corresponding bond lengths and bond angles reported for closely related compounds (Yuan et al., 2011; Krebs et al., 2001). The tetracyclic ring system is essentially planar (maximum deviation = 0.032 (2) Å). The dihedral angle between the fluorobenzene ring and the phenanthrene tetracyclic system is 60.83 (4)° and to that of the benzene ring of methoxybenzene is 80.55 (5)°. The dihedral angle between the methoxybenzene and the fluorobenzene rings is 69.45 (6)°. The maximum deviation of C8 atom from the mean plane of the methoxy benzene is -0.021° and that of C7 atom from that of fluorobenzene is 0.059 Å.

In the crystal packing, the molecules are linked by C—H···O intermolecular interactions into infinite chains running paralell to the b axis. The crystal structure is further stabilized by C—H···Cg interactions (Table 1), where Cg1 is the centre of gravity of N1/C7/N2/C15/C16, Cg2 is the center of gravity of C1—C6 and Cg3 is the center of gravity of C15/C16/C17/C22/C23/C28.

Experimental top

A mixture of phenanthrene-9,10-dione (1.0 g, 4.8 mmol), ammonium acetate (1.48 g, 19.2 mmol), 4-fluorobenzaldehyde (0.6 g, 4.3 mmol) and 4-methoxy aniline (2.95 g, 24 mmol) were refluxed in ethanol (20 ml) at 353 K. The reaction was monitored by TLC and purified by coloumn chromotography using petroleum ether:ethyl acetate (9:1) as the eluent. Yield: 0.84 g(50%). The compound was dissolved in dimethyl sulfoxide and allowed to evaporate slowly, until single crystals were grown.

Refinement top

The hydrogen atoms were placed in calculated positions with C–H = 0.93 Å to 0.96 Å, refined in the riding model with fixed isotropic displacement parameters: Uiso(H) = 1.5Ueq(C)for methyl group and Uiso(H) = 1.2Ueq(C)for other groups.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles.

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.
