In the mol-ecule of the title compound, C(15)H(14)N(4), the triazole ring is oriented at dihedral angles of 30.8 (2) and 67.4 (2)° with respect to the pyridine and benzene rings, respectively. The crystal structure is stabilized by C-H⋯N hydrogen-bonding inter-actions, forming chains of mol-ecules along [01].
In the title compound, C26H37N5S, the piperazine ring adopts a chair conformation with the exocyclic N-C bonds in pseudo-equatorial orientations. The piperazine ring (all atoms) subtends dihedral angles of 79.47 (9) and 73.07 (9)° with the triazole and benzene rings, respectively, resulting in an approximate U-shape for the mol-ecule. No significant inter-molecular inter-actions are observed in...
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.
In the title mol-ecule, C(17)H(16)N(4)O, the triazole ring makes dihedral angles of 29.00 (1) and 77.74 (1)°, respectively, with the phenyl and benzene rings. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extending along the c axis.
Bulky alkylzinc complexes, (Ttz(tBu,Me))ZnMe and (Ttz(tBu,Me))ZnEt, show remarkable stability towards water and both complexes crystallize with one molecule of adventitious water hydrogen bonded to two triazole rings; in contrast the less bulky complex, (Ttz(Ph,Me))ZnEt, reacts with water to yield (Ttz(Ph,Me))(2)Zn.
In the title mol-ecule, C(11)H(11)N(3)O(2), the dihedral angle between the benzene and triazole rings is 76.47 (10)°. The crystal structure exhibits inter-molecular O-H⋯N hydrogen bonds, which lead to the formation of helical chains along [001].
In the title mol-ecule, C(17)H(11)F(2)N(3)O, the triazole ring makes dihedral angles of 83.00 (5) and 16.63 (5)°, respectively, with the phenyl and benzene rings. Weak inter-molecular C-H⋯F and C-H⋯N inter-actions contribute to the crystal packing.
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.
In the title mol-ecule, C(23)H(20)N(4)O(2)S, the triazole ring forms dihedral angles of 150.3 (2), 77.3 (2) and 77.6 (2)°, respectively, with the furan ring and the phenyl rings. The furan ring is almost perpendicular to the central phenyl ring, making a dihedral angle of 86.0 (3)°.
In the title compound, C(14)H(10)BrN(5)S, the dihedral angle between the triazole ring and the pyridine and bromo-benzene rings are 26.42 (13) and 6.28 (13)°, respectively. The molecule exists as a thione in the solid state. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating [010] C(8) chains.
