In the title compound, [Cu(C9H6N3O2)2(H2O)4].2H2O, the Cu(II) atom lies on an inversion center and is 6-coordinated by 2 N atoms from 2 4-(1,2,4-triazol-4-yl)benzoate ligands and 4 water mols. in a distorted octahedral geometry. In the crystal, intermol. O-H…O H-bonds lead to a 3D supramol. network. Intramol. O-H…N H-bonds and π-π interactions between the benzene rings and between the benzene and triazole rings [centroid-centroid distances = 3.657(1) and 3.752(1) Å] are observed Crystal data: triclinic, P1̅, a = 7.3001(4), b = 7.9904(5), c = 9.8995(6) Å, α = 85.343(1)°, β = 73.243(1)°, γ = 79.032(1)°, Z = 1, 2025 observed reflections with I > 2σ(I), 178 refined parameters, R[F2 > 2σ(F2)] = 0.034, wR(F2) = 0.091. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2SDS of cas: 157069-48-2).
4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2) belongs to triazole derivatives. Triazoles exhibit substantial isomerism, depending on the positioning of the nitrogen atoms within the ring. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.SDS of cas: 157069-48-2
