The aromatic rings in the title compound, C13H8ClNO4, enclose a dihedral angle of 39.53 (3)°. The nitro group is almost coplanar with the ring to which it is attached [dihedral angle = 4.31 (1)°]. In the crystal, molecules are connected by C—H⋯O hydrogen bonds into chains running along [001].

2-Chlorobenzoyl chloride was added drop wise to the solution of 4-nitrophenol (in a mixture of dry tetrahydrofuran (THF) and triethyl amine). The reaction mixture was stirred at room temperature for two hours and then was poured into the cold water. The oily product settled down after allowing the solution to stand for two hours, the supernatant liquid was decanted. The product was extracted from the solution by extraction with ethyl acetate, washed with 10% NaHCO3 solution to remove any traces of reactants and recrystallized from methanol. Yield 78%, m.p. 416–418 K.
All H atoms were initially located by difference Fourier synthesis. Subsequently all H atoms were refined using a riding model with C—H = 0.95 Å and with Uiso(H) = 1.2Ueq(C).
The aromatic
like 4-Nitrophenyl-2-chlorobenzoate, can be used as starting materials for the synthesis of several pain-relieving and anti-inflammatory drugs (Selvakumar et al., 2002; Jefford & Zaslona, 1985).The two aromatic rings in the title compound enclose a dihedral angle of 39.53 (3)°. The nitro group is almost coplanar with the phenyl ring to which it is attached [dihedral angle 4.31 (1)°]. In the crystal, the molecules are connected by C—H···O bonds to chains running along [0 0 1].

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 aromatic esters, like 4-Nitrophenyl-2-chlorobenzoate, can be used as starting materials for the synthesis of several pain-relieving and anti-inflammatory drugs (Selvakumar et al., 2002; Jefford & Zaslona, 1985).
The two aromatic rings in the title compound enclose a dihedral angle of 39.53 (3)°. The nitro group is almost coplanar with the phenyl ring to which it is attached [dihedral angle 4.31 (1)°]. In the crystal, the molecules are connected by C—H···O bonds to chains running along [0 0 1].
