Abstract
3,5-Dichloro-3',4'-dimethoxybiphenyl, C(14)H(12)Cl(2)O(2), is a dihydroxylated metabolite of 3,4-dichlorobiphenyl (PCB 14). The title compound displays π-π stacking interactions between inversion related chlorinated benzene rings, with an inter-planar stacking distance of 3.3695 (17) Å. The dihedral angle between the two benzene rings was 42.49 (6)°. The methoxy groups on the non-chlorinated ring lie essentially in the plane of the benzene ring, with dihedral angles of 4.0 (2)° and -2.07 (19)°.
