1-Methyl-4H-3,1-benzoxazine-2,4(1H)dione
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...
متن کامل6-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.
متن کامل8-Methoxy-3-methyl-3,4-dihydro-2H-1,3-benzoxazine
The title compound, C10H13NO2, crystallizes with two crystallographically independent mol-ecules of similar geometry in the asymmetric unit; the six-membered oxazine rings adopts a half-chair conformation. Neither hydrogen bonds nor π-π inter-actions are observed in the crystal structure.
متن کامل3-Methyl-4H-chromen-4-one
In the title chromenone derivative, C(10)H(8)O(2), the two fused six-membered rings are coplanar, with a mean deviation of 0.0261 (1) Å from the plane through the non-H atoms of the rings. The carbonyl and methyl substituents of the pyran ring also lie close to that plane, with the O and C atoms deviating by 0.0557 (1) and 0.1405 (1) Å, respectively. In the crystal, weak C-H⋯O contacts form cha...
متن کامل4-Methyl-2,4,6-triphenyl-4H-thiopyran
The six-membered thio-pyran ring in the title compound, C(24)H(20)S, adopts a flattened boat conformation, with the S atom displaced by 0.273 (2) Å and the 3-methyl-ene C atom by 0.294 (3) Å from the plane of the other four sp(2)-hydridized C atoms. The methyl group on the methyl-ene carbon lies in a axial position with the phenyl equatorial.
