The mol-ecule of the title compound, C(24)H(32)N(4)OS, is a functionalized 1,3,4-oxadiazole-2-thione with substituted piperazine and adamantanyl substituents attached at the 3- and 5-positions, respectively, of the oxadiazole spacer with an approximately C-shaped conformation. In the crystal, mol-ecules form dimers via C-H⋯S inter-action. The piperazine ring has a chair conformation; the substi...

We report the synthesis and characterisation of the new polytopic ligands, ddta (N,N-di(pyridin-2-yl)-4,6-di(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)-1,3,5-triazin-2-amine) and tptd (N(2),N(2),N(4),N(4)-tetra(pyridin-2-yl)-6-(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)-1,3,5-triazine-2,4-diamine). Each contains N-donor dipyridylamino binding sites as well as separate and distinct mono-...

There are two unique mol-ecules in the asymmetric unit of the title pyridine-thione derivative, C(6)H(7)NS, each of which adopts the thione rather than the mercaptan form. The rings in both mol-ecules are essentially planar, with maximum deviations from the least-squares planes through all non-H atoms of 0.021 (2) and 0.017 (2) Å. In the crystal structure, the mol-ecules form centrosymmetric cy...

The title compound was obtained in high yield the reaction between tryptamine and naproxen. newly synthesized naproxen derivative fully analyzed characterized via 1H, 13C-NMR, UV, IR, mass spectral data.

In the title compound, C(20)H(13)N(3)S, the partially saturated ring adopts a twisted half-boat conformation with the methyl-ene C atom closest to the amino-benzene ring lying 0.690 (6) Å out of the plane defined by the five remaining atoms. The dihydro-phenanthrene residue has a folded conformation [dihedral angle between the outer benzene rings = 26.27 (18)°]. The thio-phen-2-yl ring forms a ...
