1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. Triazoles are important five-member nitrogen heterocycles involved in a wide range of industrial applications such as agrochemicals, corrosion inhibitors, dyes, optical brighteners, as well as biologically active agents. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeCOA of Formula: C4H3N3O4

Flexible Mixed-Spin Kagome ́Coordination Polymers with Reversible Magnetism Triggered by Dehydration and Rehydration was written by Zhang, Wei-Xiong;Xue, Wei;Chen, Xiao-Ming. And the article was included in Inorganic Chemistry in 2011.COA of Formula: C4H3N3O4 This article mentions the following:

Two new two-dimensional (2D) heterometal coordination polymers [Cu2M(tzdc)2(H2O)2]·2H2O [M = Fe2+ (1) or Mn2+ (2); tzdc3- = 1,2,3-triazole-4,5-dicarboxylate] were assembled by using the tzdc3-, Cu2+, and Fe2+/Mn2+ ions. Single-crystal x-ray anal. reveals that the two compounds consist of mixed-spin microporous Kagome layers, which are packed into three-dimensional structures by H bonding and interlayer weak Cu···O interactions. When heated, they can release in a stepwise manner the uncoordinated and coordinated H2O mols. to produce dehydrated phases (1‘ and 2‘), resp., which are stable up to ∼300°. The structures of 1‘ and 2‘ were determined by powder x-ray diffraction anal., which reveals a change in the coordination sphere of Fe2+/Mn2+ ions from an octahedron to an elongated 4+2 form, and a microporous-to-nonporous structural transformation involving intralayer wrinkling and interlayer superimposition. When the dehydrated samples are exposed to air, they can return to the hydrated phases quickly by adsorption of H2O mols. Accordingly, a reversible change in magnetism between the ferrimagnetic character of the hydrated samples and the suppressed ferrimagnetic character of the dehydrated samples was found in this reversible dehydration and rehydration. These facts indicate these 2-dimensional heterometal coordination polymers are unique flexible 2-dimensional dynamic magnetic materials. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6COA of Formula: C4H3N3O4).
