In the title resonance conformer, C(15)H(12)ClNO(4), the central C-N bond [1.297 (2) Å] has considerable double-bond character and the N-O bond [1.3215 (18) Å] indicates formal negative charge on the oxygen atom. Considerable deviations from co-planarity are evident in the mol-ecule, with both benzene rings twisted out of the central C-C-N-C plane [the dihedral angle formed between the rings = 81.99 (8)°]. Similarly, the carboxylic acid residue occupies a position almost normal to the plane of t ...[more]
