In the title compound, C12H12N6S, the dihedral angles between the central pyrazole ring and the pendant triazole and benzene rings are 68.01 (4) and 59.83 (9)°, respectively. In the crystal, mol-ecules are linked by N-H⋯N and N-H⋯S hydrogen bonds, generating (10-1) sheets.
متن کامل(±)-3-(5-Amino-3-methyl-1-phenyl-1H-pyrazol-4-yl)-2-benzofuran-1(3H)-one
In the title compound, C18H15N3O2, the benzo-furan ring system is essentially planar, the rings making a dihedral angle of 0.57 (9)°. The phenyl, furan and benzene rings subtend dihedral angles of 47.07 (10), 85.76 (7) and 86.04 (7)°, respectively, with the pyrazole ring. In the crystal, mol-ecules are linked by weak N-H⋯N, N-H⋯O and C-H⋯O inter-actions, generating edge-fused R 4 (4)(20), and R...
متن کامل3-{1-[4-(2-Methylpropyl)phenyl]ethyl}-4-phenyl-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C(20)H(23)N(3)S, the central 1,2,4-triazole ring makes dihedral angles of 69.76 (9) and 81.69 (8)°, respectively, with the phenyl and benzene rings. In the crystal, mol-ecules are linked into a centrosymmetric dimer by a pair of inter-molecular N-H⋯S hydrogen bonds, generating an R(2) (2)(8) ring motif.
