The asymmetric unit of the title compound, C16H14O4, consists of one half-molecule of an essentially planar biphenyldicarboxylic acid ester, with the complete molecule generated by an inversion centre. The maximum deviation from a least-squares plane through all non-H atoms occurs for the peripheric methyl groups and amounts to 0.124 (2) Å. The solid represents a typical molecular crystal without classical hydrogen bonds. The shortest intermolecular contacts do not differ significantly from the sum of the van der Waals radii of the atoms involved.
