The asymmetric unit of the title compound, C(20)H(18)ClN(5)O(3)S, contains two independent mol-ecules with significantly different conformations of the heterocyclic thia-zine rings. In both mol-ecules, the thia-zine rings adopt half-chair conformations, with the S atoms displaced by 0.382 (3) and 0.533 (3) Å and N atoms -0.351 and -0.275 Å, respectively, from the planes formed by the remaining ...
In the title compound, C17H17N3O3S, the cyclo-pentane ring is disordered over two sets of sites with an occupancy ratio of 0.775 (8):0.225 (8) for the affected atoms. The thia-zolidinyl ring is planar (r.m.s. deviation = 0.024 Å) and forms a dihedral angle of 65.13 (8)° with the attached phenyl ring. The mol-ecular packing is stabilized by C-H⋯O and C-H⋯π inter-actions, forming a three-dimensio...
In the title compound, C(19)H(16)N(4)S(4), the mol-ecules exhibit a butterfly conformation, where the thia-diazole and attached benzene rings in two wings are almost coplanar, with dihedral angles of 0.8 (3) and 0.9 (3)°, respectively, while the two thia-diazole rings form a dihedral angle of 46.3 (3)°.
In the title compound, C(14)H(17)NO(5)S, the thia-zine ring adopts a half-chair conformation. The mol-ecule exhibits an intra-molecular O-H⋯O hydrogen bond, which forms a six-membered S(6) ring motif. The planes of the benzene and thia-zine rings are inclined at a dihedral angle of 15.30 (12)°.
The title mol-ecule, C(8)H(6)BrNS(2), is almost planar with a dihedral angle of 0.9 (1)° between the benzene and thia-zole rings. The values of the geometry-based index of aromaticity (HOMA) and the nucleus-independent chemical shift (NICS) for the two cyclic fragments of the title mol-ecule are 0.95 and -9.61, respectively, for the benzene ring, and 0.69 and -7.71, respectively, for the thia-z...
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(9)H(11)NOS, the thia-zolidinyl ring is almost perpendicular to the phenyl ring with N-C-C-C torsion angles of 71.7 (2) and 107.1 (2)°. In the crystal, mol-ecules are connected via N-H⋯O and O-H⋯N hydrogen bonds, forming layers.
In the title compound, C(10)H(6)FNO(2)S, the benzene and thia-zolidine rings make a dihedral angle of 7.52 (3)°. Intra-molecular C-H⋯O and C-H⋯S hydrogen bonds result in the formation of nearly planar five- and six-membered rings; the adjacent rings are nearly coplanar. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.
In the title compound, C(16)H(20)N(2)O(3)S, the thia-zolidine ring is approximately planar [maximum deviation = 0.020 (2) Å] and forms a dihedral angle of 86.20 (11)° with the benzene ring. The mean plane through the propanamide unit forms dihedral angles of 88.54 (12) and 76.36 (12)°, respectively, with the thia-zolidine and benzene rings. In the crystal structure, mol-ecules are linked into c...
In the title compound, C(17)H(22)N(4)O(3)S, the dihedral angle between the planes of the thia-diazole and phenyl rings is 63.47 (7)°. The dihedral angle between the thia-diazole ring and the acetamide side chain is 7.72 (9)°. Mol-ecules related by a 2(1) screw axis along the a axis are linked by inter-molecular N-H⋯O hydrogen bonds generating a supra-molecular chain.
