In the title mol-ecule, C(22)H(17)ClN(2)O(5), the nitro-substituted benzene ring makes a dihedral angle of 79.22 (1)° with the benzoyl ring and 53.03 (1)° with the chloro-substituted benzene ring. An intra-molecular C-H⋯O hydrogen bond occurs. The crystal structure features weak C-H⋯Cl and C-H⋯O inter-actions.
