The title compound, C(12)H(20)N(6)O(2), has a centre of symmetry. The mol-ecule consists of two triazole rings joined by an aliphatic -(CH(2))(6)- chain. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds and by π-π stacking inter-actions between the triazole rings of inversion-related mol-ecules [centroid-centroid distance = 3.277 (8) Å].
In the title compound, C(12)H(12)N(6)·4H(2)O, the two triazole rings adopt a cis configuration with a crystallographic twofold axis passing through the central benzene group. The benzene and triazole rings are almost coplanar with a dihedral angle of 5.5 (1)°. In the crystal, water mol-ecules are joined together by OW-H⋯OW hydrogen bonds to form a one-dimensional zigzag chain. These water chain...
In the title compound, C(16)H(15)N(3)O(2)·H(2)O, the two benzene rings and the triazole ring lie almost in the same plane, the triazole ring forming dihedral angles of 5.07 (9) and 5.80 (8)° with the benzene rings. In the crystal, there are three relatively strong inter-molecular O-H⋯N and N-H⋯O hydrogen bonds, which lead to the formation of a one-dimensional double chain running parallel to th...
The asymmetric unit of the title compound, C(10)H(12)N(4)OS, contains two independent mol-ecules, A and B, which differ significantly in the relative orientations of the benzene and triazole rings. The dihedral angle between the above two rings is 6.94 (5)° in mol-ecule A and 77.60 (5)° in mol-ecule B. In the crystal, mol-ecules are linked into a three-dimensional network by N-H⋯S, N-H⋯O, N-H⋯N...
In the title compound, C(11)H(9)Cl(2)N(3)O(3), the triazole and benzene rings are roughly parallel to one another [dihedral angle = 4.99 (2)°] because the C-O-C-C-O chain that links the two rings is folded [O-C-C-O = 8.60 (2)°] rather than fully extended. In the crystal, weak inter-molecular C-H⋯N and C-H⋯O inter-actions are present, and π-π inter-actions are indicated by the short distances [3...
The title compound, C(14)H(17)N(5)O, a 1,2,3-triazole derivative of benzoxadiazole (C(14)H(17)N(5)O), was synthesized via Cu-catal-ysed azide-alkyne cyclo-addition (CuAAC) from the corres-ponding n-octyne and 4-azido-benzoxadiazole. The benz-oxa-diazole and triazole rings show a roughly planar orientation [dihedral angle between the ring planes = 12.18 (5)°]. The alkane chain adopts a zigzag co...
In the title mol-ecule, C(9)H(7)N(7), the two triazole rings are twisted by an angle of 3.8 (5)°; the central triazole ring is twisted by 32.3 (6)° with respect to the pyridyl ring. The crystal packing consists of layers generated by inter-molecular N-H⋯N hydrogen bonds.
In the title compound, C(20)H(16)N(4), the m-tolyl and phenyl substituents form dihedral angles of 74.20 (6) and 36.94 (8)°, respectively, with the 1,2,4-triazole ring and the dihedral angle between the triazole and pyridine rings is 36.06 (9)°. In the crystal, mol-ecules are linked by C-H⋯N and C-H⋯π inter-actions.
The title compound, C(11)H(13)N(5), is a Schiff base synthesized by the reaction of 4-amino-4H-1,2,4-triazole and 4-(dimethyl-amino)-benzaldehyde. The dihedral angle between the benzene and triazole rings is 43.09 (11)°. The crystal structure displays weak C-H⋯N inter-actions.
In the title compound, C26H34F2N6S, the triazole ring is linked to a benzene ring via an imine bond [N=C = 1.255 (2) Å; conformation: E], with a dihedral angle of 25.21 (11)° between the rings. The 4-ethyl-piperazinyl residue is folded away from the thione-S atom. In the crystal, helical supra-molecular chains propagating along [010] and sustained by weak C-S⋯π(triazole) inter-actions occur [S⋯...
