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

Abstract

In the title compound, C(14)H(9)ClN(2)O, the quinazoline unit is essentially planar, with a mean deviation from the least-squares plane defined by the ten constituent ring atoms of 0.027 (2) Å. The dihedral angle between the mean plane of the quinazoline ring system and the 4-chloro-phenyl ring is 44.63 (5)°. 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.
