In the title mol-ecule, C(10)H(9)BrN(4)S, the dihedral angle between the triazole and benzene rings is 12.32 (19)°. An intra-molecular C-H⋯S hydrogen bond generates an S(6) ring motif. In the crystal packing, centrosymmetrically related mol-ecules are linked into a dimer by N-H⋯S hydrogen bonds, and the dimers are linked into a chain running along [11] by Br⋯N short contacts [3.187 (3) Å]. The ...

In the mol-ecule of the title compound, C(24)H(20)N(4)O(2)S, the dihedral angle between the triazole and thio-phene rings is 66.80 (4)° and the dihedral angle between the two benzene rings is 63.37 (4)°. An intra-molecular C-H⋯O inter-action results in the formation of a six-membered ring. A π⋯π contact between the benzene rings, [centroid-centroid distance = 3.918 (2) Å] may stabilize the stru...

The title compound, C(20)H(19)N(5)O(2), exhibits whole-mol-ecule disorder the refined ratios of the two components being 0.57 (2):0.43 (2). In the major component, the essentially planar [maximum deviation 0.033 (17) Å] fused pyrimidine and triazole ring system forms a dihedral angle of 10.5 (3)° with the phenyl ring, while in the minor component of disorder this angle is 27.5 (5)°. The crystal...

The title compound, C20H23N3O6·CH3OH, was synthesized by [3 + 2] cyclo-addition of (Z)-2,3-bis-(3,4,5-tri-meth-oxy-phen-yl)acrylo-nitrile with sodium azide and ammonium chloride in DMF/water. The central nitro-gen of the triazole ring is protonated. The dihedral angles between the triazole ring and the 3,4,5-tri-meth-oxy-phenyl ring planes are 34.31 (4) and 45.03 (5)°, while that between the 3,...

The title mol-ecule, C(19)H(19)FN(4)S, displays C(s) mol-ecular symmetry, in which the crystallographic mirror plane bis-ects the adamantan-1-yl unit while the 3-fluoro-phenyl triazole ring is located on the mirror plane. The F atom of the 3-fluoro-phenyl ring is positionally disordered [occupancy ratio 0.9:0.1]. In the crystal, π-π inter-actions between the triazole and phenyl rings occur [cen...
