By using solvothermal method, two novel coordination polymers based on 4-(4-carboxyphen-yl)-1,2,4-triazole (Hcpt) and Zn(II) cations, [Zn(cpt)(OH)]n·nH2O (FJU-32) and [Zn(cpt)(atrz)]n (FJU-33) (Hatrz = 3-amino-1,2,4-triazolate), were synthesized and characterized by single-crystal X-ray diffraction analyses, elemental analyses, FT-IR and powder X-ray diffraction. FJU-32 crystallizes in monoclinic, space group P21/c with a = 3.7441(3), b = 23.0384(19), c = 11.8562(10) Å, β = 99.069(8)°, V = 1009.91(15) Å3, Dc = 1.898 g/cm3, C9H9N3O4Zn, Mr = 288.57, F(000) = 916, μ(MoKα) = 2.439 mm-1, Z = 4, R = 0.0600 and wR = 0.1306 for 2412 observed reflections (I > 2σ (I)), and R = 0.0704 and wR = 0.1349 for all data. FJU-33 crystallizes in monoclinic space group P2 1/c with a = 12.7483(5), b = 9.9922(3), c = 9.8403(3) Å, β = 100.756(4)°, V = 1231.47(7) Å3, Dc = 1.816 g/cm3, C11H9N7O2Zn, Mr = 336.62, F(000) = 680, μ(CuKα) = 2.957 mm-1, Z = 4, R = 0.0478 and wR = 0.1184 for 2466 observed reflections (I > 2σ (I)), and R = 0.0687 and wR = 0.1309 for all data. In FJU-32, Zn(II) is coordinated to three μ3-OH groups forming an unprecedented 1D zigzag-like double chain, and the 1D double chains are connected to four neighboring double chains by the cpt ligands to form an extended 3D porous coordination polymer. In FJU-33, the adjacent [Zn(atrz)] 2D layers are further connected by the cpt ligands via Zn-O coordinated bonds and neighboring interlayer hydrogen-bonding interactions to give rise to an overall 3D pillared layer structure. The neutral triazole group of the cpt ligand has weaker coordination ability than the triazolate anion of atrz ligand. Furthermore, FJU-32 and FJU-33 display high thermal stability up to 300°, and the solid state fluorescence reveals that two new complexes are potential optical materials. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2Related Products of 157069-48-2).
4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2) belongs to triazole derivatives. Triazoles consist of a five-membered ring containing three nitrogen atoms and are biologically active, especially as antifungal, antimicrobial and enzyme inhibitors. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeRelated Products of 157069-48-2
