In the title mol-ecule, C(31)H(26)N(4)O(2)S, the phenyl ring attached to the 1,2,4-triazole ring forms dihedral angles of 65.4 (2), 63.4 (2) and 62.2 (2)° with the other three rings. The 1,2,4-triazole ring makes dihedral angles of 78.0 (2), 87.9 (2), 24.9 (2) and 62.8 (2)° with three phenyl rings and the methoxyphenyl ring.
In the title mol-ecule, C(17)H(11)Cl(2)N(3)O, the C=C bond connecting the triazole and 4-chloro-phenyl groups adopts a Z geometry. The dihedral angles formed by the triazole ring and the 4-chloro substituted benzene rings are 67.3 (1) and 59.1 (1)°. The dihedral angle between the two benzene rings is 73.5 (1)°.
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...
In the title compound, [Zn(C11H7N6)2(H2O)2], the Zn(II) cation, located on an inversion center, is N,N'-chelated by two 5-(pyrazin-2-yl)-3-(pyridin-3-yl)-1,2,4-triazolide anions and is further coordinated by two water mol-ecules in a distorted N4O2 octa-hedral geometry. In the anionic ligand, the pyrazine and pyridine rings are twisted with respect to the central triazole ring by 5.77 (10) and ...
In the mol-ecule of the title compound, C(18)H(19)N(3)O(3), the triazole ring is oriented with respect to the 3-methoxy-phenyl and 2-methoxy-phenyl rings at dihedral angles of 11.79 (3) and 89.22 (3)°, respectively. The dihedral angle between the two benzene rings is 85.95 (3)°. In the crystal structure, inter-molecular O-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules. There is a π-π contact ...
The title compound, a bis-5,5'-triazole, C(38)H(28)N(6)O(4), was observed as a side-product from the Sharpless-Meldal click reaction of the corresponding coumarin alkyne and benzyl-azide. Although the compound was present as a minor component, it crystallized in preference to the major product. The two triazole rings are almost orthogonal to each other [dihedral angle = 83.8 (1)°]. However the ...
In the title compound, C(15)H(12)Cl(2)N(4)S·C(15)H(10)Cl(2)N(4)S·C(2)H(6)O, the two chloro-phenyl rings of the triazole derivative form dihedral angles of 65.7 (2) and 44.2 (2)° with the triazole ring. In the thio-carbonohydrazide derivative, the dihedral angle between the two chloro-phenyl rings is 5.4 (2)°. In the crystal, the triazole, thio-carbonohydrazide and methanol mol-ecules are linked...
In the title compound, C13H11N3S2, the triazole and thio-phene rings are coplanar [dihedral angle = 6.22 (13)°]. By contrast, the phenyl ring is perpendicular to the triazole ring [dihedral angle = 85.58 (13)°], so that the mol-ecule has an L-shape. The thio-phene S atom is syn with the ring imine N atom. In the crystal, eight-membered {⋯HNCS}2 synthons form between centrosymmetrically related ...
In the title mol-ecule, C(17)H(11)N(11), the five rings are almost coplanar [maxium deviation 0.1949 (1) Å]. The dihedral angles between the two pyrazine rings and the two triazole rings are 1.52 (4) and 2.51 (5)°, respectively. The central pyridine ring forms dihedral angles of 5.57 (1) and 1.71 (1)° with the two triazole rings. The crystal packing consists of a three-dimensional network struc...
In the mol-ecule of the title compound, C(15)H(13)Cl(2)N(3)O(2), the triazole ring is oriented at dihedral angles of 2.54 (13) and 44.43 (12)°, respectively with respect to the furan and dichloro-benzene rings. The dihedral angle between the dichloro-benzene and furan rings is 46.75 (12)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric di...
