Abstract
In the title compound, C26H20O4, the complete molecule is generated by a crystallographic 2-fold axis and the naphthalene ring system is planar within 0.05 (4) Å. The dihedral angles between the –COO plane, the benzene ring and naphthalene ring system are 12.83 (3) and 12.93 (1)°, respectively. The –COO plane and the benzene ring are almost coplanar, forming a dihedral angle of 2.59 (8)°.
