1H-1,2,4-Triazole-3-carboxamide
Planar mol-ecules of the title compound, C(3)H(4)N(4)O, are organized into sheets by extensive N-H⋯O and N-H⋯N hydrogen bonding in the (101) plane of the crystal structure. These hydrogen bonds may also stabilize the mol-ecule in the Z form. The title compound is in the amide form, as shown by the C=O bond length [1.252 (2) Å].

In the mol-ecule of the title compound, C(18)H(16)F(2)N(4)O(2), the 1,2,4-triazole ring forms dihedral angles of 3.6 (2) and 14.9 (6)° with the 4-difluoro-meth-oxy-substituted benzene ring and the 2,3-dimethyl-substituted benzene ring, respectively. The OCHF(2) group is twisted away from the plane of the benzene ring, as shown by the C-O-C-C torsion angle of 145.8 (2)°. The conformation is stab...
متن کامل1-[4-(Difluoromethoxy)phenyl]-N-(3,4-dimethoxyphenyl)-1H-1,2,4-triazole-3-carboxamide
Two crystallographically independent mol-ecules, A and B, with similar conformations are present in the asymmetric unit of the title compound, C(18)H(16)F(2)N(4)O(4). In mol-ecule A, the plane of the 1,2,4-triazole ring is tilted relative of the 4-difluoro-meth-oxy-substituted and the 3,4-dimeth-oxy-substituted benzene rings by 6.5 (2) and 16.4 (1)°, respectively. The -CHF(2) group is twisted a...
متن کامل3-Nitro-1H-1,2,4-triazole
The asymmetric unit of the title compound, C(2)H(2)N(4)O(2), contains two crystallographically independent mol-ecules in which the triazole rings are essentially planar, with maximum deviations of 0.003 (1) Å in both molecules. The dihedral angle between the two 1H-1,2,4-triazole rings is 56.58 (5)°. In the crystal, mol-ecules are linked via inter-molecular N-H⋯N and C-H⋯O hydrogen bonds, formi...
متن کاملAcetylation of methyl 5-amino-1H-[1,2,4]triazole-3-carboxylate.
Acetylation with acetic anhydride of methyl 5-amino-1H-[1,2,4]triazole-3-carboxylate, one of the hetareneamino acids, was studied using HPLC, H NMR, FTIR and GC-MS. The compound has a significantly decreased susceptibility to acetylation compared to 5-amino-1H-[1,2,4]triazole itself. Two isomeric diacetylated products were found.
