3,3′-Bis(4-chlorophenyl)-2,2′-(m-phenylenedioxy)diquinazolin-4(3H)-one

Abstract

In the title compound, C34H20Cl2N4O4, the two quinazoline heterocyclic systems and the adjacent chlorobenzene rings are not coplanar, but oriented at dihedral angles of 66.66 (13) and 52.48 (12)°, respectively. The quinazoline ring systems are nearly planar, with dihedral angles between the planes of the two rings of 5.43 (16) and 3.40 (14)°, and are oriented at dihedral angles of 79.73 (13) and 83.52 (13)° with respect to the adjacent benzene ring between them. Intermolecular C—H...O hydrogen bonds contribute to the stability of the structure. In addition, weak π–π stacking interactions [centroid-to-centroid distances = 3.872 (1) and 3.876 (1) Å] are observed in the crystal structure.
