6-Chloro-8-methyl-4H-3,1-benzoxazine-2,4(1H)-dione
The two mol-ecules in the asymmetric unit of the title compound, C(9)H(6)ClNO(3), are nearly planar, with r.m.s. deviations of 0.034 and 0.037 Å. The crystal structure is stabilized by two weak inter-molecular N-H⋯O inter-actions.

In its crystal structure, the title compound, C(9)H(7)NO(3), forms π-stacked dimers, with a centroid-centroid distance of 3.475 (5) Å between the benzenoid and the 2,4 dicarbonyl oxazine rings. These dimers then form staircase-like linear chains through further π-stacking between the benzenoid rings [centroid-centroid distance of 3.761 (2) Å]. The methyl-H atoms are disordered due to rotation a...

In the title compound, C11H7ClO3, a chlorinated and methyl-ated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0670 Å), with the largest deviation from the least-squares plane [0.2349 (17) Å] being for the pyran carbonyl O atom. In the crystal, mol-ecules are linked through π-π stacking inter-actions along the a axis [centroid-centroid distance betw...

In the title compound, C10H4ClNO5, the non-H atoms of the 6-chloro-chromone unit are coplanar (r.m.s. deviation = 0.017 Å) with the largest deviation from the mean plane [0.031 (2) Å] being found for the C=O C atom. The nitro group (NO2) is inclined to the chromone unit mean plane by 13.3 (2) °. The formyl group is also twisted with respect to the attached ring [C-C-C-O torsion angles = 10.8 (4...

The mol-ecule of the title compound, C(11)H(7)ClO(3), is planar, with a maximum deviation of 0.0383 (10) Å from the naphthoquinone plane. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds. Short intra-molecular Cl⋯O [2.8234 (8) Å] and O⋯O [2.5530 (11) Å], and inter-molecular Cl⋯Cl [3.2777 (3) Å] contact...
