In the racemic title compound, C17H15ClN2O4, which has been synthesized and the crystal structure of the solvent-free molecule determined, the angle between the planes of the benzene and cyclopropane rings is 54.29 (10)°. The molecular conformation is stabilized by two weak intramolecular C-H. Ocarboxyl interactions. In the crystal, C-H. O hydrogen bonds form centrosymmetric cyclic R2 2(10) dimers which are linked into chain substructures extending along c. Further C-H. Nnitrile hydrogen bonding, including a centrosymmetric cyclic R2 2(14) association, link the chain substructures, forming a two-dimensional layered structure extending across the approximate ab plane. No significant π-π or halogen-halogen intermolecular interactions are present in the crystal.
