The asymmetric unit of the title compound, C15H14ClN3O6, contains two independent molecules. The imidazole rings are oriented with respect to the benzene rings at dihedral angles of 19.66 (3) and 21.64 (3)°. In the crystal structure, intermolecular O-HN hydrogen bonds link the molecules into infinite chains.
