A series of biologically active new mixed ligand complexes of cobalt(II), nickel(II) copper(II) and cadmium(II) have been synthesized. The reactions of the Schiff base ligand 3-benzyl-1H-4-[(2-methoxybenzylidine)amino]l,2,4-triazole-5-thione(MBT);3-benzyl-1H-4-[(4chlorobenzylidine)amino]-1,2,4-triazole-5-thione(CBT); 3benzyl-1H-4-[(4-nitrobenzylidine)amino]-1,2,4-triazole-5-thione (NBT) and sod...
The title 1,3,4-oxa-diazole-2-thione derivative, C18H20N4OS2, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The 2-thienyl rings in both mol-ecules are rotationally disordered over two orientations by approximately 180° about the single C-C bond that connects it to the oxa-diazole thione ring; the ratios of site occupancies for the major and minor components were...
The reaction of 5-(1-adamantyl)-4-phenyl-1,2,4-triazoline-3-thione (compound 5) with formaldehyde and 1-substituted piperazines yielded the corresponding N-Mannich bases 6a-f. The reaction of 5-(1-adamantyl)-4-methyl-1,2,4-triazoline-3-thione 8 with various 2-aminoethyl chloride yielded separable mixtures of the S-(2-aminoethyl) 9a-d and the N-(2-aminoethyl) 10a-d derivatives. The reaction of c...
The title compound, C18H20ClN3S, is a functionalized triazoline-3-thione derivative. The benzene ring is almost perpendic-ular to the planar 1,2,4-triazole ring [maximum deviation = 0.007 (1) Å] with a dihedral angle of 89.61 (5)° between them and there is an adamantane substituent at the 3-position of the triazole-thione ring. In the crystal, N-H⋯S hydrogen-bonding inter-actions link the mol-e...
In the title complex, [W(C(3)H(6)N(2)S)(CO)(5)], the W atom displays an octa-hedral coordination with five CO mol-ecules and an imidazolidine-2-thione mol-ecule. The W(CO)(5) unit is coordinated by the cyclic thione ligand through a W-S dative bond. The W-S and C-S bond lengths are 2.599 (2) and 1.711 (9) Å, respectively. This last distance is significantly longer than that of free cyclic thio-...
The purpose of the current study was to evaluate the effect of functional monomers contained in the primers on adhesive bonding of a steel alloy. SUS XM27 steel was primed with one of the following materials; Alloy Primer, Estenia Opaque Primer, and V-Primer. The functional monomers in the primers were a phosphate (10-methacryloyloxydecyl dihydrogen phosphate; MDP) and a thione (6-(4-vinylbenzy...
The title compound, [Sn(C(6)H(5))(3)(C(9)H(10)NS(2))], has two independent mol-ecules in the asymmetric unit and each features a tetra-hedrally coordinated Sn(IV) atom as the dithio-carbamate ligand coordinates in a monodentate fashion. As the non-coordinating thione S atom is proximate to the Sn atom [Sn⋯S(thione) = 3.1477 (6) and 2.9970 (5) Å for the independent mol-ecules], distortions from ...
3-Methyl-1-phenyl-1,5-dihydro-pyrazolo[3,4-d]pyrimidine-4-thione was prepared and used as a key compound for the preparation of some S-acyclic nucleosides of pyrazolo[3,4d]pyrimidine-thiones. Furthermore, the corrosion inhibitions of the prepared compounds towards carbon steel corrosion by 1.0 M hydrochloric acid were evaluated by chemical and electrochemical methods. The effect of inhibitors c...
In the title compound, C(10)H(12)N(2)OS(2), the thione and S-methyl groups are syn. An intra-molecular bifurcated O-H⋯(S,N) hydrogen bond occurs.
