Dimethyl 3,3′-dimethoxybiphenyl-4,4′-dicarboxylate

Abstract

In the title compound, C18H18O6, the biphenyl moiety is twisted with a dihedral angle of 29.11 (10)°. The carbometh­oxy 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 meth­oxy groups. In the absence of stacking inter­actions and with no H...O contacts shorter than 2.7 Å, the packing is dominated by weaker van der Waals inter­actions.
