3,3'-Bis(4-chloro-phen-yl)-2,2'-(m-phenyl-enedi-oxy)diquinazolin-4(3H)-one.


ABSTRACT: In the title compound, C(34)H(20)Cl(2)N(4)O(4), the two quinazoline heterocyclic systems and the adjacent chloro-benzene 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. Inter-molecular C-H⋯O hydrogen bonds contribute to the stability of the structure. In addition, weak π-π stacking inter-actions [centroid-to-centroid distances = 3.872 (1) and 3.876 (1) Å] are observed in the crystal structure.
