In the title compound, C21H13BrClNO2S, the dihedral angle between the planes of the benzothiazole and chlorophenylmethanone groups is 71.34 (6)°. In the crystal, weak C—HN hydrogen bonds lead to dimer formation, whereas BrCl short contacts [3.4966 (11) Å] form infinite chains along the a-axis direction. Further, the C—HO, C—Hπ and π–π [centroid–centroid distance = 3.865 (2) Å] interactions stabilize the three-dimensional network.

In the title compound, C20H15ClIN3O3, the dihedral angle between the quinazolinone ring system [r.m.s. deviation = 0.047 (2) Å] and the pendant benzene ring is 82.63 (11)°. The molecular conformation is stabilized by intramolecular C—HO interactions. In the crystal, the molecules are linked by N—HO hydrogen bonds into chains along the a-axis direction. Another set of chains propagating along [101] is formed due to intermolecular ICl short contacts of 3.427 (1) Å, thus giving layers parallel to (010). The layers are connected by C—Hπ and π–π interactions, the shortest distance between the centroids of aromatic rings being 3.8143 (16) Å.
