In the title compound, C10H9ClN2O6, the two nitro groups and the ester group are oriented with respect to the benzene ring at dihedral angles of 49.42 (13)/87.61 (13) and 9.10 (10)°, respectively. In the a weak C—H⋯O interaction is present. A short Cl⋯O contact of 2.972 (2) Å is also observed in the crystal structure.

Commercial isopropyl 4-chloro-3,5-dinitrobenzoate was recrystallized by slow evaporation of methanol solution. Colourless single crystals were formed after several weeks.
H atoms were placed in calculated positions and were allowed to ride on the parent C atoms with C—H distances of 0.95 (aromatic), 0.98 (methyl) and 1.00 Å (methine); Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for the others.
Isopropyl 4-chloro-3,5-dinitrobenzoate (Fig. 1) is a useful herbicide and fungicide (Akira et al., 1978; Ferenc et al., 1984). It was used as the acid compounds to combat fungal diseases and weeds. We report here the
of the title compound. Two nitro groups (O3/ N1/O4 and O5/N2/O6) attached at C2 and C4, the ester group (O1/C7/O2) attached at C6 form dihedral angles of 49.4 (1)°, 87.6 (1)° and 9.1 (1)° with the mean plane of the C1-benzene ring, respectively. In the adjacent molecules are linked together by the weak C—H···O hydrogen bonds (Table 1).For the application of the title compound as a herbicide and fungicide, see: Akira et al. (1978); Ferenc et al. (1984).

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. |

Isopropyl 4-chloro-3,5-dinitrobenzoate (Fig. 1) is a useful herbicide and fungicide (Akira et al., 1978; Ferenc et al., 1984). It was used as the acid compounds to combat fungal diseases and weeds. We report here the crystal structure of the title compound. Two nitro groups (O3/ N1/O4 and O5/N2/O6) attached at C2 and C4, the ester group (O1/C7/O2) attached at C6 form dihedral angles of 49.4 (1)°, 87.6 (1)° and 9.1 (1)° with the mean plane of the C1-benzene ring, respectively. In the crystal structure, adjacent molecules are linked together by the weak C—H···O hydrogen bonds (Table 1).
