The title compound, C(12)H(10)N(2)O(2)·H(2)O, crystallizes as a zwitterion in which the pyridine N atom is protonated and the carboxyl OH group is deprotonated. The benzene and pyridinium rings are inclined at a dihedral angle of 54.93 (1)°. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network.

In the title mononuclear complex, [Zn(N(3))(2)(C(8)H(8)N(6))(2)], the Zn(II) atom, lying on a twofold rotation axis, is six-coordinated in a distorted octa-hedral environment by four N atoms from two 2,4-diamino-6-(2-pyrid-yl)-1,3,5-triazine ligands and two N atoms from two end-on-coordinated azide ions. N-H⋯N hydrogen bonds between the ligand and azide ion link the complex mol-ecules into a th...

The self-assembly of 2,4,6-tris(pyridin-4-yl)-1,3,5-triazine (tpt) triangular panels with p-cymene (p-Pr(i)C(6)H(4)Me) ruthenium building blocks and 2,5-dioxydo-1,4-benzoquinonato (dobq) bridges, in the presence of a functionalised pyrenyl derivative (pyrene-R), affords the triangular prismatic host-guest compounds [(pyrene-R) [symbol: see text] Ru(6)(p-Pr(i)C(6)H(4)Me)(6)(tpt)(2)(dobq)(3)](6+)...

The title compound, C(14)H(6)Cl(6)N(2)OS·0.5CHCl(3), crystallizes with four 1-(2,6-dichloro-benzo-yl)-3-(2,3,5,6-tetra-chloro-phen-yl)thio-urea mol-ecules and two trichloro-methane mol-ecules in the asymmetric unit. The thiourea molecules exist in the solid state in their thione forms with typical thio-urea C-S and C-O bonds lengths, as well as shortened C-N bonds. The -NH-C(=S)-NH-C(=O)- plane...

A series of 1-(2-hydroxyethyl)-3,5-dimethylpyrazolylazo derivatives, incorporating thiosemicarbazide 2a-c, 1,3,4-thiadiazole 3a-c, and 1,2,4-triazole-3-thione 4a-c were synthesized. The structure of these novel synthesized compounds 2a-c, 3a-c, and 4a-c was confirmed by spectral analysis. All these compounds were screened for their analgesic activity. Hot-plate and tail-immersion tests were use...
