1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides. 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.Computed Properties of C4H3N3O4

Coordination-driven self-assembly of Cp*Rh-based rectangles in novel families of hetero-bimetallic metal-organic frameworks was written by Lin, Lin;Lin, Yue-jian;Jin, Guo-xin. And the article was included in Applied Organometallic Chemistry in 2019.Computed Properties of C4H3N3O4 This article mentions the following:

The crystal and mol. structures of structurally related 1,2,3-triazole-4,5-dicarboxylate (LHtzdc = 1,2,3-triazole-4,5-dicarboxylate) ligands for 2nd metal ions were established via single-crystal x-ray structural anal. [Cu (en)]2+ (en = ethylenediamine) was selected as a 2nd metal ion, the two spare sites of the O atom from LHtzdc are coordinated to a single [Cu (en)]2+, and the [Cu (en)]2+ metal centers act as two outer pockets, which is an effective and innovative method of controlling the assembly of heterometallic cages. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Computed Properties of C4H3N3O4).
