6-Bromo-4-(2-cyclohexylidenehydrazin-1-ylidene)-1-methyl-2,2-dioxo-3,4-dihydro-1H-2λ6,1-benzothiazine
The asymmetric unit of the title compound, C(15)H(18)BrN(3)O(2)S, contains two independent mol-ecules in both of which the (thia-zine)C=N-N double bond exhibits an E conformation. The cyclo-hexyl rings adopt chair conformations while the thia-zine rings are in sofa conformations. The mean planes of these rings are oriented at dihedral angles of 64.43 (13) and 28.6 (2)° in the two independent mo...

In the title compound, C(16)H(15)N(3)O(3)S, the dihedral angle between the aromatic rings is 8.18 (11)° and the C=N-N=C torsion angle is 178.59 (14)°. The conformation of the thia-zine ring is an envelope, with the S atom displaced by 0.8157 (18) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.045 Å). An intra-molecular O-H⋯N hydrogen bond closes an S(6) ring. In the crystal...

In the title compound, C(16)H(13)BrN(4)O(4)S, the dihedral angle between the aromatic rings is 4.1 (2)° and the C=N-N=C torsion angle is 175.5 (3)°. The nitro group is almost coplanar with the benzene ring to which it is attached [dihedral angle = 2.9 (7)°]. The thia-zine ring has an S-envelope conformation with the S atom displaced by 0.819 (3) Å from the mean plane of the other five atoms (r....
متن کامل1-Methyl-4-[1-(1-phenylethylidene)-hydrazin-2-ylidene]-3,4-dihydro-1H-2λ6,1-benzothiazine-2,2-dione
In the title compound, C(17)H(17)N(3)O(2)S, the phenyl ring is oriented at dihedral angles of 8.5 (2) and 1.17 (14)°, respectively, to the C=N-N plane and the fused aromatic ring. The thia-zine ring adopts an envelope conformation with the S atom at the flap. In the crystal, a weak C-H⋯O inter-action connects the mol-ecules, forming a helical chain along the a axis.

In the title mol-ecule, C(12)H(13)N(5)O(2)S, a bifurcated intra-molecular N-H⋯O(O) hydrogen bond forms two S(6) ring motifs. The benzene ring forms a dihedral angle of 14.36 (11)° with the pyrazole ring. In the crystal, pairs of N-H⋯S hydrogen bonds form centrosymmetric dimers, generating R(2) (2)(8) ring motifs, which stack along the b axis.
