3-(4-Bromo-phen-yl)quinazolin-4(3H)-one

Abstract

In the title compound, C(14)H(9)BrN(2)O, the quinazoline unit is essentially planar, with a mean deviation of 0.058 (2) Å from the least-squares plane defined by the ten constituent ring atoms. The dihedral angle between the mean plane of the quinazoline ring system and the 4-bromo-phenyl ring is 47.6 (1)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯N and C-H⋯O hydrogen bonds, forming infinite chains of alternating R(2) (2)(6) dimers and R(2) (2)(14) ring motifs.
