1-(4-Meth-oxy-phen-yl)ethane-1,2-diyl 1,1'-biphenyl-2,2'-dicarboxyl-ate.
In the title mol-ecule, C(23)H(18)O(5), the meth-oxy-substituted benzene ring makes dihedral angles of 65.12 (4) and 88.55 (4)° with the other two benzene rings. These two benzene rings form a dihedral angle of 45.70 (4)°. In the crystal, mol-ecules are linked into inversion dimers by pairs of weak C-H⋯O hydrogen bonds.
