In the presence of MeI or EtI, N-tert-butyl-1,3-thiazoline-2-thione derivatives undergo a transformation to 2-alkylthio-thiazoledithiolate pro-ligands with elimination of the tert-butyl substituent. The corresponding Au(III) dithiolene complexes [Au(RS-tzdt)2](-) (R = Me, Et) oxidize readily to the neutral radical species, such as the semi-conducting [Au(EtS-tzdt)2]˙, which organizes into dimer...

A number of benzothiazole-2-ylsulfanyl derivatives 2(1,3-Benzothiazol-2-ylsulfanyl)alkanoylhydrazide (IA – IG) and 5-[1-(1,3-Benzothiazol-2-ylsulfanyl)alkyl]-1,3,4-thiadiazole-2(3H) thione (IIA-IIG) have been synthesised from (1,3Benzothiazol-2-ylsulfanyl)acetic acid. These compounds were synthesied and characterized from their F.T.I.R, and H-NMR spectral studies. The compound (IIA to IIG) were...

The title compound, C26H42N4O2S2, adopts a shallow U-shape as both pendant arms of the 1,3-substituted benzene ring are orientated in the same direction. The thione S atoms lie to the same side of the benzene ring and the carbonyl O atoms to the other. The most prominent feature of the crystal packing is the formation of inversion dimers mediated by N-H⋯S hydrogen bonds. One of the 2-methyl-pro...

In the title complex, [Ni(C(7)H(14)N(4)OS)(2)]Cl(2), the Ni(II) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from the two imine and two oxime groups, and two S atoms from the thione groups. Two chloride ions complete the asymmetric unit. In the crystal, mol-ecules are linked through N-H⋯Cl and O-H⋯Cl hydrogen bonds into an infinite chain propagating along [101].

The title mol-ecule, C(13)H(17)ClN(2)O(3)S, shows an anti and syn disposition of the butanoyl and 2,5-dimethoxyphenyl groups with respect to the thione and is stabilized by intra-molecular N-H⋯O and weak C-H⋯S hydrogen bonds. In the crystal, inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal structure is stabilized by weak C-H⋯O and C-H⋯S contacts.

The title compound, C(15)H(12)N(2)OS, exists as the thione tautomer in the solid state. The phenyl group is almost perpendicular [dihedral angle = 87.96 (5)°] to the fused ring system (r.m.s. deviation = 0.036 Å for 13 ring and exocyclic non-H atoms). In the crystal, centrosymmetric dimers, sustained by pairs of N-H⋯S hydrogen bonds, are connected into layers parallel to (-101) by C-H⋯O and C-H...

In the title compound, C9H10N4OS, the dihedral angle between the benzene and 1H-1,2,4-triazole-5(4H)-thione rings is 67.51 (16)°. In the crystal, mol-ecules are liked via N-H⋯O hydrogen bonds, forming chains along the c-axis direction. The chains are linked via O-H⋯S hydrogen bonds, forming corrugated layers lying parallel to the bc plane. The layers are linked via N-H⋯N and N-H⋯S hydrogen bond...

A series of benzimidazole-2-thione derivatives was synthesized using a reaction between the macrocyclic aminal 16H,13H-5:12,7:14-dimethanedibenzo[d,i]-[1,3,6,8] tetraazecine (DMDBTA, 5) and various nucleophiles in the presence of carbon disulfide. A full chemical characterization using IR, ¹H-, ¹³C-NMR and GC-MS analyses of the new compounds is provided. These compounds were separated from the ...

In the title compound, C(17)H(18)N(2)O(2)S, the 1,3-diazinane-2-thione ring system is not coplanar with the benzene ring and meth-oxy-phenyl ring system, the dihedral angle between the planes being 65.58 (13) and 89.18 (10)°, respectively. The crystal structure is characterized by inter-molecular O-H⋯S, N-H⋯S, N-H⋯O and C-H⋯S hydrogen bonding.

The asymmetric unit of the title compound, C(14)H(18)N(2)S, contains two independent and conformationally similar mol-ecules, which form cyclic dimers via inter-molecular hydrogen bonds of the type N-H⋯S [graph set R(2) (2)(8)]. The structure is iso-morphous with that of one of the polymorphs of 4,4,6-tri-methyl-1-phenyl-3,4-dihydro-pyrimidine-2(1H)-thione [Yam-in et al. (2005 ▶). Acta Cryst. E...
