In the title compound, C18H18O6, the biphenyl moiety is twisted with a dihedral angle of 29.11 (10)°. The carbometh-oxy groups form C-C-C-O torsion angles of -18.3 (3) and -27.7 (3)° with the attached rings, as a result of steric hindrances from the nearby meth-oxy groups. In the absence of stacking inter-actions and with no H⋯O contacts shorter than 2.7 Å, the packing is dominated by weaker van der Waals inter-actions.
在标题化合物C₁₈H₁₈O₆中，联苯部分扭转，二面角为29.11 (10)°。由于附近甲氧基的空间位阻，甲氧基羰基与相连环形成的C-C-C-O扭转角分别为-18.3 (3)°和-27.7 (3)°。在没有堆积相互作用且不存在短于2.7 Å的H⋯O接触的情况下，堆积主要由较弱的范德华相互作用主导。
