In the title compound, C14H7N3O3, the dihedral angle between the two arene units is 62.57 (12)°.
o-nitrophenol (1.39 g, 10.0 mmol) and 3-nitrophthalonitrile (1.73. g, 10.0 mmol) were dissolved in dry DMF (15 ml) with stirring under N2. Dry fine-powdered potassium carbonate (2.5 g, 18.1 mmol) was added over the course 1 h in equal portions every 10 min. The reaction mixture was stirred for 48 h at room temperature and poured into iced water (150 g). The product was filtered off and washed with(10% w/w) NaOH solution and water until the filtrate was neutral. Recrystallization from ethanol gave a white product (yield 1.72 g, 65%). Single crystals were obtained from absolute ethanol at room temperature via slow evaporation (m.p. 397–400 K). IR data (ν _max/cm-1): 3050(Ar—H), 1591(NO2), 2230(CN). NMR δ(H) 7.34–7.39(1H, m), 7.53–7.63(2H,m), 7.81–7.93(3H,m), 8.19–8.26(1H,m).
H atoms were included as riding atoms in geometrically idealized positions with C—H distances 0.93 Å and Uiso(H) = 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. |

Phthalonitriles are among the most important precursors of phthalocyanine materials (Leznoff, 1989–1996). Monophneoxyphthalonitriles have been used for preparing symmetrical phthalocyanines which have been applied in many areas, such as laser printing, photocopying, optical data storage, and catalysis (McKeown, 1998).
In the title compound, (I), (Fig. 1) the triple bond lengths between C and N, 1.136 (5) Å and 1.129 (5) Å, agree with literature values (Ocak et al., 2003). The geometry around the O atoms is in good agreement with the literature (Atalay et al., 2003, 2004; Köysal et al., 2004). The dihedral angle between the two intramolecular arene moieties is 62.57 (12)°.
