The title compound, C 18 H 16 O 2 , was prepared using literature procedures and crystallized from an acetone-toluene solution (50:50 v/v). The dihedral angle between the two aromatic rings is 9.28 (8) A Λ. The crystal packing is stabilized by van der Waals forces.

The title compound, C~17~H~12~Cl~2~O, crystallizes in a centrosymmetric space group. The dihedral angle between the two benzene rings is 24.7β (1)Β°. The crystal packing is characterized by non-classical CβH...O and CβH...Cl inter- and intramolecular hydrogen bonds.
In the title compound, C 17 H 16 N 2 O 3 , the dihedral angle between the benzene rings is 1.56 (7) . The nitro group is coplanar with the attached benzene ring while the dimethylamino group is twisted slightly away from the attached benzene ring. A weak intramolecular C-HΓ Γ ΓO hydrogen bond is pre
