Abstract: The title compound, C11H15ClN2O2, lies on a crystallographic mirror plane of symmetry; thus all of its atoms, except for two of the tert-butyl methyl C atoms and the H atoms, are exactly coplanar. There is an intramolecular hydrogen bond between the amide N atom and a nitro O atom. There are no exceptionally close intermolecular contacts, but the planar portions of the molecules stack with their planes only 3.39 Å apart.
