Abstract
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 Å, respectively] connect the layers.

As a contribution to a structural study of biphenyl ether derivatives we report here the title compound methyl-(3′,4′,5′-trimethoxybiphenyl)-4-carboxylate (I)
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
