The asymmetric unit of the title compound, C(10)H(9)NO(5)S, contains two independent mol-ecules. The heterocyclic thia-zine rings in both mol-ecules adopt half-chair conformations, with the S atoms in each mol-ecule displaced by 0.455 (3) and 0.539 (3) Å and the N atoms displaced in the opposite direction by 0.214 (3) and 0.203 (3) Å, from the planes defined by the remaining ring atoms. The cry...

The title compound, C(15)H(8)Cl(2)N(2)O(2)S, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the 4-chloro-3-nitro-phenyl ring and the thia-zole ring are 0.5 (1) and 7.1 (1)° and those between the 4-chloro-phenyl ring and the thia-zole ring are 7.1 (1) and 7.4 (1)° in the two mol-ecules. The crystal structure is stabilized by inter-molecular C-H⋯Cl and C-H⋯O ...

In the title compound, C(10)H(11)N(3)O(2)S, the thia-zine ring exists in a conformation inter-mediate between twist-boat and half-chair. The dihedral angle between the mean plane of the thia-zine ring and the hydrazide group is 89.45 (13)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into (100) sheets and weak C-H⋯O inter-actions further consolidate the packing.

In the crystal structure of the title compound, C(17)H(18)N(2)O(4)S(3), mol-ecules are connected into centrosymmetric dimers via weak inter-molecular C-H⋯π inter-actions. These dimers are further connected through a series of weak C-H⋯O hydrogen bonds, while futher C-H⋯π inter-actions involving the phenyl and thia-zoline rings are also observed. The thia-zolidine ring is twisted from the benzen...

Sung Kwon Kang Nam Sook Cho Siyoung Jang

In the title compound, C(12)H(12)N(6)S(4), the two terminal thia-diazole rings are twisted with respect to the central benzene ring, making dihedral angles of 54.28 (4) and 76.56 (3)°. The dihedral angle between the two thia-diazole rings is 27.77 (4)°. Inter-molecular N-H⋯N hydrogen bonds stabilize the crystal packing, linking the mol-ecules into a tape along the b axis.

In the mol-ecule of the title compound, C(17)H(15)N(3)O(3)S·0.5H(2)O, the thia-diazole ring is oriented with respect to the two 2-methoxy-phenyl rings at dihedral angles of 3.70 (3) and 1.74 (2)°. An intra-molecular N-H⋯O hydrogen bond results in the formation of a planar six-membered ring, which is oriented with respect to the thia-diazole ring at a dihedral angle of 1.33 (3)°. Thus, all of th...

In the title compound, C21H19NO2S2, the seven-membered thia-zepine ring adopts a slightly distorted twist boat conformation. The dihedral angle between the benzene rings is 67.4 (2)°. The mean plane of the thio-phene ring is twisted by 59.3 (2) and 87.7 (2)° from the mean planes of the benezene rings. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R 2 (2)(20) ...
