Abstract

The title compound, C(28)H(22)Cl(2)N(2)O(2), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the outer aromatic rings. These dihedral angles are 56.07 (13) and 27.62 (15) Å for mol-ecules A and B, respectively. In the crystal, A mol-ecules are related as centrosymmetric pairs through a weak π-π inter-action [centroid-centroid distance = 3.6959 (15) Å]. There are also a number of inter-molecular C-H⋯O, C-H⋯N and C-H⋯π inter-actions present.
