title: 3,5-Dinitro-benzoyl chloride.
abstract: The carbonyl chloride group in the title compound, C(7)H(3)ClN(2)O(5), is disordered over two orientations with occupancies of 0.505 (5) and 0.495 (5). The mol-ecule 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.
