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 compound, [ZnCl(2)(C(9)H(17)N(3)S)(2)], the Zn(II) atom is four-coordinated by two N atoms from two 5-heptyl-1,3,4-thia-diazol-2-amine ligands and two Cl atoms in a distorted tetra-hedral geometry. The thia-diazole rings are oriented at a dihedral angle of 84.87 (4)°. Intra-molecular N-H⋯Cl inter-actions result in the formation of two six-membered rings having envelope and planar c...

The title compounds, 6-(2-hy-droxy-benz-yl)-5H-thia-zolo[3,2-a]pyrimidin-5-one, C13H8N2O3S, (1), and 6-(2-hy-droxy-benz-yl)-3-methyl-5H-thia-zolo[3,2-a]pyrimidin-5-one, C14H10N2O3S, (2), were synthesized when a chromone-3-carb-oxy-lic acid, activated with (benzotriazol-1-yl-oxy)tripyrrolidinyl-phospho-nium hexa-fluorido-phosphate (PyBOP), was reacted with a primary heteromamine. Instead of the ...

The mononuclear title complex, [Cu(SCN)2(C12H8N4S)2], was obtained by the reaction of 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole and potassium thio-cyanate with copper(II) chloride dihydrate. The copper cation lies on an inversion centre and displays an elongated octa-hedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazo...

In the title compound, C14H19BrN2O2S, the 1,2,4-thia-diazinane ring adopts an envelope conformation with the N atom (attached to the sulfonyl group) as the flap, while the cyclo-hexane ring adopts a chair conformation. The mean plane of the cyclo-hexane ring is almost normal to the benzene ring and the mean plane of the 1,2,4-thia-diazinane ring, making dihedral angles of 70.4 (2) and 71.43 (19...

In the title compound, C(16)H(16)N(2)O(3)S·C(5)H(5)N, the benzene and thia-zole rings of the Febuxostat [2-(3-cyano-4-isobut-yloxy)phenyl-4-methyl-5-thia-zolecarboxylic acid] mol-ecule are almost coplanar [dihedral angle = 2.4 (1)°]. The carboxyl group is coplanar with the thia-zole ring [O-C-C-C and O-C-C-S torsion angles of -0.7 (4) and 0.6 (3)°, respectively]. The pyridine mol-ecule of cryst...

In the title compound, C39H36N2O4S, the piperidine ring adopts a twisted half-chair conformation. In the pyrrolo-thia-zole fused-ring system, the pyrrole ring adopts an envelope conformation (with the C atom bound to the thia-zole ring being the flap atom) and the thia-zole ring also exhibits an envelope conformation (with the N atom bound to the pyrrole ring as the flap). The mol-ecular struct...

We report the synthesis and total NMR characterization of 5-thia-1-azabicyclo-[4.2.0]oct-2-ene-2-carboxylic acid-3-[[[(4''-nitrophenoxy)carbonyl]oxy]-methyl]-8-oxo-7-[(2-thienyloxoacetyl)amino]-diphenylmethyl ester-5-dioxide (5), a new cephalosporin derivative. This compound can be used as the carrier of a wide range of drugs containing an amino group. The preparation of the intermediate produc...

In the title compound C(19)H(11)N(3)O(2)SClBr·C(2)H(6)OS, 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, with maximum deviations of 0.027 (2) and 0.003 (1) Å, respectively. The central thia-zole ring makes dihedral angles of 21.82 (9) and 5.88 (7)° with the chloro-substituted phenyl ring and th...
