Methyl 3',5'-dimeth-oxy-biphenyl-4-carboxyl-ate.

In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16)°. In the crystal, the mol­ecules are packed in an anti­parallel fashion in layers along the a axis. In each layer, very weak C—H⋯O hydrogen bonds occur between the meth­oxy and methyl ester groups. Weak C—H⋯π inter­actions between the 4′- and 5′-meth­oxy groups and neighbouring benzene rings [meth­oxy-C–ring centroid distances = 4.075 and 3.486 A, respectively] connect the layers.
