1-Methyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide
In the crystal structure of the title compound, C(9)H(9)NO(3)S, there is distorted tetra-hedral geometry around the S atom. The sulfonyl group is almost normal to the benzene ring, while the carbonyl O atom and methyl C atom are on opposite sides of this ring. The heterocyclic ring adopts a half-boat conformation with the S atom out of the plane. The mol-ecules are dimerized by hydrogen bonding...
متن کامل1-Methyl-3-phenylquinoxalin-2(1H)-one
The phenyl substituents in both independent mol-ecules of the title compound, C(15)H(12)N(2)O, are twisted with respect to the quinoxaline system [dihedral angles = 19.3 (1) and 30.4 (1)°].

The ten-membered fused ring of the title compound, C(12)H(10)N(2)O, is essentially planar in the two independent mol-ecules of the asymmetric unit (r.m.s. deviations = 0.012 and 0.015 Å).
متن کامل4-Methyl-1-phenylquinolin-2(1H)-one
In the title compound, C(16)H(13)NO, the mol-ecules are connected three-dimensionally through non-classical C-H⋯O and C-H⋯π inter-actions of 3.272 (3), 3.380 (3) and 3.382 (4) Å. Classical hydrogen bonds are not observed. The dihedral angle between the benzyl and quinolin-2(1H)-one mean planes is 87.15 (7)°
متن کامل6-Bromo-1-methyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide
In the crystal structure of the title compound, C(9)H(8)BrNO(3)S, the thia-zine ring is in the twisted form. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds form inversion dimers with an R(2) (2)(8) ring motif. Weak inter-molecular C-H⋯Br and C-H⋯π inter-actions are also present.
