چکیده
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.

In the centrosymmetric title compound, C(34)H(30)F(2)N(6)O(4), the dihedral angle between the quinazolinone and fluorobenzene ring planes are 71.00 (2) and 74.94 (2)° and an intra-molecular N-H⋯O interaction stabilizes the conformation. In the crystal, C-H⋯F and C-H⋯O links help to establish the packing.

The two title compounds, C28H26N2O2, (I), and C27H22BrClN2O2, (II), differ in their substituents, viz.4-methyl-phenyl and benzoyl rings in (I) replaced by 2-chloro-phenyl and 4- bromo-benzoyl, respectively, in (II). A significant difference between the two mol-ecules is found in the deviation of the benzoyl O atom from the least-squares plane of the ring to which it is attached [0.593 (4) and 0...
