The title salt, [Ni(C3H2NS2)(C12H8N2)2]PF6·1.5C4H8O2, was the unexpected product on making an attempt to prepare an [Ni(2-mercapto-thia-zol-ate)(1,10-phenanthroline)]+ complex by reaction of [NiCl2(1,10-phen-an-throline)] with 2-mercapto-thia-zolate. In the resulting complex, the 2-mercapto-thia-zolate anion acts as a chelating ligand, which coordinates to the NiII ion with the thia-zolyl N and...

Crystals of the title compound, C(11)H(9)N(5)O(4)S, were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and methyl 1,3-thia-zol-2-yl ketone. Excluding two methyl H atoms, the mol-ecule displays a planar structure, the dihedral angle between the terminal thia-zole and benzene rings being 1.82 (8)°. The imino group links with adjacent nitro and thia-zole groups by intra-mol...

Reaction of N3,N8-diacyl 6-thia-3,8-diazabicyclo/3.2. l./octan-2-one (I) with PC15 or S02Cl2 gave 6-chloro substituted N2,N5-diacyl 7-thia-2,5-diazabicyclo/2.2.2./octan-3-one (II). Treatment of II with water yielded the 6-hydroxy derivative (III) while reaction with methanol gave the 6-methoxy derivative (IV). Under the same reaction conditions the mono N8-acyl derivative (V) gave a mixture of ...

The structural analysis of the title compound, C14H14N2O4S, particularly the presence of an acetyl group at the exocyclic N atom and the C(H)-C(O2CMe)-N acet-oxy group in the thia-zole ring, may indicate that one of the starting materials, i.e. 2-(4-meth-oxy-anilino)-1,3-thia-zol-4(5H)-one, exists in the reaction mixture, at least partially, as a tautomer with an exocyclic amine N atom and an e...

In the title mol-ecule [systematic name: 10-(prop-2-yn-1-yl)dipyrido[3,4-b:3',4'-e][1,4]thia-zine], C(13)H(9)N(3)S, the dihedral angle between the two pyridine rings is 146.33 (7)° and the angle between two halves of the thia-zine ring is 138.84 (8)°, resulting in a butterfly shape for the tricyclic system. The central thia-zine ring adopts a boat conformation, with the 2-propynyl substituent a...

In the title compound, C17H15NO2S, the thia-zepine ring adopts a slightly distorted twist-boat conformation. The dihedral angle between the mean plane of the benzo-thia-zepin ring system and the benzene ring is 65.7 (1)°. In the crystal, pairs of N-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers, generating R2 (2) (8) ring motifs. These dimers are further linked by C-H⋯π and π-...

The title compound, C(8)H(5)BrN(4)O(2)S, was synthesized by the reaction of 4-bromo-2-nitro-benzoic acid with thio-semi-carbazide. The dihedral angle between the thia-diazole and benzene rings is 40.5 (2)°. In the crystal, the strongest N-H⋯N inter-molecular hydrogen bond, between the amine group and one thia-diazole N atom, forms centrosymmetric dimers. The other amine H atom extends the supra...

In the racemic title compound, C19H14N2OS, the two phenyl substituents on the 1,3-thia-zine ring are almost perpendicular to the pyridine ring which is fused to the thia-zine ring [inter-ring dihedral angles = 87.90 (8) and 85.54 (7)°]. The dihedral angle between the two phenyl rings is 75.11 (7)°. The six-membered thia-zine ring has an envelope conformation with the ortho-related C atom formin...

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, ...
