7-Chloro-6,8-dinitroquinazolin-4(3H)-one acetic acid monosolvate

Abstract

In the title compound, C8H3ClN4O5·C2H4O2, both the nitro groups are close to perpendicular [dihedral angles = 67.62 (15) and 86.73 (12)°] to the almost planar quinazoline unit [r.m.s. deviation = 0.014Å]. In the crystal, both the quinazoline and acetic acid molecules form inversion dimers linked by pairs of N—H...O and O—H...O hydrogen bonds, respectively. R22(8) loops arise in each case.
