3,5-Di-chloro-3′,4′-di-meth-oxy-biphen-yl

摘要

The title compound, C 14 H 12 Cl 2 O 2 , is a dimethoxylated derivative of 3,4-di-chloro-biphenyl (PCB 14). The dihedral angle between the benzene rings is 42.49?(6)°. The meth-oxy groups on the non-chlorinated ring lie essentially in the plane of the benzene ring, with C—C—O—C torsion angles of 4.0?(2) and ?2.07?(19)°. In the crystal, the compound displays π – π stacking inter-actions between inversion-related chlorinated benzene rings, with an inter-planar stacking distance of 3.3695?(17)??.
