4-Hydrazinylidene-1-methyl-3H-2λ6,1-benzothiazine-2,2-dione
In the title compound, C(9)H(11)N(3)O(2)S, the thia-zine ring adopts a half-chair conformation. In the crystal structure N-H⋯N hydrogen bonds connect two mol-ecules into a centrosymmetric dimer, forming an R(2) (2)(6) ring motif. These dimers are further connected into chains by N-H⋯O and C-H⋯O hydrogen bonds.

In the title compound, C(17)H(16)BrN(3)O(2)S, the two fused rings are twisted by a dihedral angle of 6.61 (15)°. The thia-zine ring adopts a sofa conformation. The toluene ring is oriented at dihedral angles of 15.5 (2) and 20.6 (2)° with respect to the bromo-benzene and thia-zine rings, respectively. The benzyl-idene system is approximately planar [r.m.s. deviation = 0.0388 Å]. In the cyrstal,...

In the title compound, C(18)H(15)NO(3), the pyridine-2,6-dione ring adopts an envelope conformation. The phenyl ring lies approximately perpendicular to the mean plane of the pyridine-2,6-dione ring [dihedral angle = 81.5 (1)°], while the methoxy-phenyl ring is tilted to the same plane by a dihedral angle of 34.8 (1)°. Inter-molecular C-H⋯O inter-actions link the mol-ecules into chains along [1...

In the title mol-ecule, C(9)H(10)BrN(3)O(2)S, the thia-zine ring has an envelope conformation with the S atom at the flap. The geometry around the S atom is distorted tetra-hedral. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, generating R(2) (2)(6) ring motifs. N-H⋯O hydrogen bonds and C-H⋯O inter-actions connect the dimers, forming a three-dimentional network...
