Abstract

In the title compound, C13H7Cl3O2, the dihedral angle between the benzene rings is 82.1 (2)°. The dihedral angle between the CO2 group and its carbon-bonded ring is 14.50 (19)° In the crystal, aromatic π–π stacking inter­actions [minimum ring centroid separation = 3.604 (2) Å] occur.

Highlights

  • In the title compound, C13H7Cl3O2, the dihedral angle between the benzene rings is 82.1 (2)

  • All su's are estimated from the variances of the variance-covariance matrix

  • Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors
