Crystal structure of (Z)-2,3-dichloro-1,4-bis(4-methoxyphenyl)but-2-ene-1,4-dione
The title compound, C18H14Cl2O4, adopts a Z conformation around the cental C=C bond. The two aromatic rings of the molecule are nearly perpendicular to each other, with a dihedral angle between of 86.22 (14)°. The methoxy substituents lie close to the plane of the attached benzene rings. The C(ar)—C...

| Summary: | The title compound, C18H14Cl2O4, adopts a Z conformation around the cental C=C bond. The two aromatic rings of the molecule are nearly perpendicular to each other, with a dihedral angle between of 86.22 (14)°. The methoxy substituents lie close to the plane of the attached benzene rings. The C(ar)—C(ar)—O—C(Me) torsion angles are −2.4 (7) and 7.5 (6)°. Weak C—H...O interactions link the molecules forming a three-dimensional network. The crystal packing also displays short [3.160 (3) Å] Cl...O halogen-bonding contacts between molecules related by the screw axis. The structure exhibits disorder of one carbonyl O atom with a refined occupancy ratio of 0.21 (6):0.79 (6). |
