The title compound, C 16 H 14 O 3 , crystallizes in the triclinic system, with two independent molecules in the asymmetric unit; these are related by a non-crystallographic twofold rotation axis. The two molecules differ slightly in the relative orientation of the two aromatic rings. They are linked
