2,6-Bis(4H-1,2,4-triazol-4-yl)pyridine dihydrate
The asymmetric unit of the title compound, C(9)H(7)N(7)·2H(2)O, comprises three formula units. The dihedral angles between the triazole rings and the respective central pyridine rings are 4.87 (16)/1.39 (17), 6.46 (16)/7.61 (16) and 7.00 (16)/3.77 (17)°. The water mol-ecules form O-H⋯O hydrogen bonds between themselves and O-H⋯N hydrogen bonds with the N-atom acceptors of the triazole rings, pr...

The asymmetric unit of the title compound, C(10)H(8)N(6)·2H(2)O, comprises half the organic species, the mol-ecule being completed by inversion symmetry, and one water mol-ecule. The dihedral angle between the 1,2,4-triazole ring and the central benzene ring is 32.2 (2)°. The water mol-ecules form O-H⋯N hydrogen bonds with N-atom acceptors of the triazole rings. C-H⋯N hydrogen bonds are also ob...
متن کاملBis(4H-1,2,4-triazol-3-yl)disulfane
The title compound, C(4)H(4)N(6)S(2), was synthesized by the reaction of 3-mercapto-1H-1,2,4-triazole with sodium hydrox-ide in ethanol. The mol-ecule possesses a crystallographically imposed twofold axis. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains along the c axis.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(16)H(10)F(6)N(4)O. The triazole ring is not coplanar with the quinoline ring system; the dihedral angle between the two planes being 74.47 (12) and 63.97 (13)° in the two mol-ecules. The crystal structure is characterized by inter-molecular C-H⋯F, C-H⋯N and C-H⋯O hydrogen bonding. Weak intra-molecular C-H⋯F int...

The asymmetric unit of the title compound, (C(8)H(8)N(5))(2)[Ce(NO(3))(5)(H(2)O)(2)], contains one independent protonated 4-pyridyl-methyl-eneamino-1,2,4-triazole cation and half of a centrosymmetric [Ce(NO(3))(5)(H(2)O)(2)](2-) anion. The Ce atom coordinated by five NO(3) (-) anions and two water mol-ecules, exhibiting a distorted 10-coordination. In the crystal structure, inter-molecular O-H⋯...
