The molecular skeleton of the title molecule, C16H11NO3, is nearly planar with the two aromatic rings forming a dihedral angle of 2.73 (7)°. In the crystal, weak intermolecular C—H⋯O hydrogen bonds link molecules into ribbons extended along [101]. The crystal packing exhibits also π–π interactions, as indicated by the short centroid–centroid distances between the aromatic rings [3.681 (3) Å] and between the aromatic and furan rings [3.811 (3) Å] of neighbouring molecules.

A solution of ethyl 2-benzoyl-4-(4-nitrophenyl)-4-oxobutanoate (0.353 g, 0.7 mmol) in ionic liquid [bmim]HSO4 (1.6 g, 6.7 mmol) was stirred at 150 °C for 4 h in oil bath. After cooling to r.t., the reaction mixture was extracted with diethyl ether thoroughly. The combined extracts were washed with water, brine,dried (Na2SO4),and filtered. The solvents were removed and the residue was purified by flash
(petroleum ether / dichloromethane 2:1) to get Ethyl 5-(4-nitrophenyl)-2-phenylfuran-3-carboxylate (240 mg, 71%) and the title compound (50 mg,14%) as yellow crystals.All H-atoms were positioned geometrically and refined using a riding model, with d(C—H) = 0.95 Å, Uiso=1.2Ueq(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. |

The title compound, (I), has been obtained as a by-product in our ongoing research of highly substituted furan derivatives (Wang et al., 2009).
In (I) (Fig. 1), two aromatic rings form a dihedral angle of 2.73 (7) °. Weak intermolecular C—H···O hydrogen bonds (Table 1) and π-π stacking interactions with centroid-centroid separations of 3.681 (3) and 3.811 (3) Å consolidate the crystal packing.
