The carbonyl chloride group in the title compound, C7H3ClN2O5, is disordered over two orientations with occupancies of 0.505 (5) and 0.495 (5). The molecule is approximately planar, the dihedral angle between the carbonyl chloride plane and benzene ring being 9.6 (4)° in the major disorder component and 7.1 (4)° in the minor component. The nitro group at the 5-position is twisted, forming a dihedral angle of 6.7 (4)°. The crystal packing is stabilized by C—H⋯O hydrogen bonds.

A sample of commercial 3,5-dinitrobenzoylchloride (Aldrich) was crystallized by slow evaporation of a solution in carbon tetrachloride.
The carbonyl chloride group is disordered over two orientations with occupancies of 0.505 (5) and 0.495 (5). The CO distance involving disordered atoms was restrained to 1.22 (1) Å and in each disorder component and the carbonyl chloride group was restrained to be planar. The displacement parameters of atoms CL1', O1', O1 and O3 were restrained to an approximate isotropic behaviour. H atoms were positioned geometrically (C—H = 0.95 Å) and were allowed to ride on the C atoms to which they are bonded, with 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. |

3,5-Dinitrobenzoyl chloride is a useful disinfectant and preservative (Saunders et al., 1942; Liu et al., 2000). It was also used as a derivatization reagent for azide determination by capillary electrophoresis (Gennaro et al., 1993). We report here the crystal structure of the title compound.
The carbonyl chloride group is disordered over two orientations (Fig. 1). Except for a long N1—O3 distance [1.339 (3) Å] all other bond lengths and angles are within expected ranges. The molecule is approximately planar. The plane of the carbonyl chloride group forms a dihedral angle of 9.6 (4)° with the benzene ring in the major component [7.1 (4)° in the minor component]. The N1/O2/O3 and N2/O4/O5 nitro groups form dihedral angles of 1.9 (3) and 6.7 (4)°, respectively, with the benzene ring.
The crystal packing is stabilized by C—H···O hydrogen bonds (Table 1).
