4-Amino-3-(4-hydroxyphenyl)-1H-1,2,4-triazol-5(4H)-one
The mol-ecule of the title compound, C(8)H(8)N(4)O(2), is nearly planar, with a dihedral angle between the rings of 1.1 (1)°. Adjacent mol-ecules are linked into a layered structure by hydr-oxy-oxo O-H⋯O and triazol-yl-hydr-oxy N-H⋯O hydrogen bonds. Only one of the H atoms of the pyramidal amino group is engaged in building up the infinite layer. The second H atom of the amino group also shows ...

The asymmetric unit of the title compound, C(3)H(4)N(4)O(2)·0.5H(2)O, comprises two whole mol-ecules of 5-amino-1H-1,2,4-triazole-3-carb-oxy-lic acid in its zwitterionic form (proton transfer occurs from the carb-oxy-lic acid group to the N hetero-atom at position 1), plus one water mol-ecule of crystallization. The organic moieties are disposed into supra-molecular layers linked by N-H⋯O and N...

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.

The asymmetric unit of the title compound, C(18)H(19)N(3)O(3), contains two crystallographically independent but similar mol-ecules. The triazole ring is oriented with respect to the benzene rings to form dihedral angles of 57.96 (6) and 7.01 (6)° in one mol-ecule, and 64.37 (5) and 10.73 (5)° in the other. The two independent mol-ecules are linked into a dimer by inter-molecular N-H⋯O hydrogen...

In the title compound, 2C(3)H(5)N(4)O(2) (+)·H(2)PO(4) (-)·NO(3) (-)·C(3)H(4)N(4)O(2), three independent 5-amino-1H-1,2,4-triazol-3-carb-oxy-lic acid moieties are observed. Two are in the form of cations, while the third is in the zwitterionic form. The triazole rings in the two cations are almost coplanar, making an angle of 4.11 (7)°. Layers parallel to the (20-1) plane, resulting from hydrog...
