And the article was included in Dalton Transactions in 2013.COA of Formula: C9H7N3O2 This article mentions the following:
Two novel Co-based metal-organic frameworks (MOFs) were synthesized and characterized using an asym. binding ligand, 4-(4′-carboxyphenyl)-1,2,4-triazole (Hcpt). The isolated [CoII3(μ3-O)(OH)(cpt)3(H2O)2]n·xH2O·yDMF, Co-MOF1, exhibits a rhombohedral crystal structure (space group, P63/mc), with a trinuclear cobalt core that resembles the MIL88 series. This MOF shows paramagnetic behavior down to 2 K with no saturation of magnetization up to 7 T. This is presumably due to a geometrically frustrated triangular arrangement of Co spins. The two-dimensional complex, [CoII(cpt)(N3)]n, Co-MOF2, crystallizes in a monoclinic crystal system (space group, C2/m). The magnetic measurements reveal metamagnetic behavior for this complex with a critical field at 700-1000 Oe. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2COA of Formula: C9H7N3O2).
4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2) belongs to triazole derivatives. Many triazoles are versatile, biologically active compounds commonly used as fungicides and plant retardants. Many triazoles have antifungal effects: the triazole antifungal drugs include fluconazole, isavuconazole, itraconazole, voriconazole, pramiconazole, ravuconazole, and posaconazole and triazole plant-protection fungicides include epoxiconazole, triadimenol, myclobutanil, propiconazole, prothioconazole, metconazole, cyproconazole, tebuconazole, flusilazole and paclobutrazol.COA of Formula: C9H7N3O2
