The asymmetric unit of the title compound, C(16)H(14)O(4), consists of one half-mol-ecule of an essentially planar biphenyl-dicarboxylic 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 mol-ecular crystal without classical hydrogen bonds. The shortest inter-molecular contacts do not differ significantly from the sum of the van der Waals radii of the atoms involved.
标题化合物C(16)H(14)O(4)的不对称单元由一个基本上呈平面状的联苯二甲酸酯的半分子组成，完整分子由一个对称中心产生。通过所有非H原子的最小二乘平面的最大偏差出现在外围甲基上，为0.124 (2) Å。该固体代表一种典型的分子晶体，不存在经典氢键。最短的分子间接触与所涉及原子的范德华半径之和没有显著差异。
