Methyl 3′,4′,5′-trimethoxybiphenyl-4-carboxylate

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.
