Abstract
In the title compound, C17H17ClO4, the dihedral angle between the mean planes of the two benzene rings is 65.92 (5)°. The methyl ester group lies within the ring plane [deviations of O atoms from the plane = −0.051 (2) and 0.151 (2) Å] due to an intramolecular O—H⋯O hydrogen bond. In the crystal, molecules are held together by rather weak non-classical intermolecular C—H⋯O hydrogen bonds, resulting in dimeric units about inversion centers, forming eight- and ten-membered ring systems as R 2 2(8) and R 2 2(10) motifs.

Summary
H atoms treated by a mixture of independent and constrained refinement max = 0.31 e Å3. R factor = 0.040; wR factor = 0.125; data-to-parameter ratio = 19.1. C17H17ClO4, the dihedral angle between the mean planes of the two benzene rings is. The methyl ester group lies within the ring plane [deviations of O atoms from the plane = 0.051 (2) and. 0.151 (2) Å] due to an intramolecular O—H O hydrogen bond. Molecules are held together by rather weak non-classical intermolecular C—H O hydrogen bonds, resulting in dimeric units about inversion centers, forming eight- and ten-membered ring systems as R22(8) and R22(10)
