In the title compound, C(20)H(14)BrN(3)O(3)S, the mol-ecule adopts an E configuration about the central C=N double bond. The chromene ring system and the thia-zole ring are approximately planar [maximum deviations = 0.029 (3) and 0.007 (3) Å, respectively]. The chromene ring system is inclined at angles of 7.37 (12) and 13.90 (13)° with respect to the thia-zole and benzene rings, respectively, ...
In the title compound, C(18)H(16)ClN(3)O(2)S, the dihedral angle between the aromatic rings is 4.81 (2)° and the alkyl chain takes on an extended conformation [N-C-C-C = 179.2 (4)°]. The conformation of the thia-zine ring is an envelope, with the S atom displaced by -0.805 (3) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.046 Å). The Cl atom is an axial conformation and is...
In the title compound, C17H12F3NO4S, the heterocyclic thia-zine ring adopts a half-chair conformation and the dihedral angle between the benzene rings is 43.28 (9)°. The α,β-unsaturated C=C group is inclined at an angle of 21.0 (3)° to the benzene ring of the benzo-thia-zine moiety. In the crystal, inversion dimers linked by pairs of carb-oxy-lic acid O-H⋯O hydrogen bonds generate R 2 (2)(8) lo...
In the structure of the title compound, C(17)H(18)ClN(3)O(4)S, the thia-zinane ring displays a twist-boat conformation. The 1,4-dihydro-pyridine ring is approximately perpendicular to the benzene ring [dihedral angle = 88.3 (1)°]. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O inter-actions into a C(8) chain al...
The title pesticide, C(17)H(21)ClN(2)O(2)S, has a trans arrangement of the 4-chloro-phenyl and 4-methyl substituents of the thia-zolidine ring; the structure features an intra-molecular amide-ring carbonyl N-H⋯O hydrogen bond. The thia-zolidine ring is almost planar, the largest deviation being 0.199 (1) Å for the methyl-substitued C atom, and the cyclohexane ring has a chair conformation.
In the title mol-ecule, C(7)H(7)N(3)S(2), the dihedral angle between the thio-phene and thia-diazole rings is 72.99 (5)°; the two rings are oriented so that the S atoms in each ring are on the same side. In the crystal, the three-dimensional network involves strong N-H⋯O hydrogen bonds, as well as C-H⋯π and π-π stacking inter-actions [centroid-centroid distances = 3.654 (1) and 3.495 (1) Å].
The title compound, C(8)H(5)FN(4)O(2)S, was synthesized by the reaction of 2-fluoro-4-nitro-benzoic acid and thio-semicarbazide. The dihedral angle between the thia-diazole and benzene rings is 27.1 (2)°. In the crystal, inter-molecular N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules.
In the racemic title compound, C20H15NO2S, the planes of the two phenyl substituents form dihedral angles of 48.97 (15) and 69.26 (15)° with that of the fused benzene ring of the parent benzo-thia-zine ring, while the heterocyclic thia-zine ring exhibits a screw-boat pucker. The O atom on the S atom of the ring is pseudo-axial on the thia-zine ring and trans to the 2-phenyl group. In the crysta...
The title compound, C(9)H(7)Cl(2)N(3)OS, was synthesized by the reaction of 2,4-dichloro-phenoxy-acetic acid and thio-semicarbazide. The dihedral angle between the thia-diazole and benzene rings is 21.5 (2)°. In the crystal, inter-molecular N-H⋯N hydrogen bonding links the mol-ecules into chains along the b axis.
In the title compound, C12H12N2OS, the dihedral angle between the benzene and thia-zole rings is 83.5 (7)°. The acetamide group is almost coplanar with the thia-zole ring, being twisted from it by 4.2 (9)°. In the crystal, pairs of N-H⋯N hydrogen bonds link mol-ecules into inversion dimers, generating R 2 (2)[8] loops; the dimers are stacked along [001].
