A new 3D Cd-triazolate framework obtained from in situ decarboxylication of 5-amino-3-carboxyl-1,2,4-triazole
چکیده انگلیسی


• 1 was obtained from decarboxylication of 5-amino-3-carboxyl-1,2,4-triazole.
• 1 is a 3D architecture based on [CdSO4] layers linking with ligand spacers.
• 1 is simplified as a (2,4,6)-connected {44.62.88.12}{44.62}{8} network.
• Thermal stability of 1 is up to 402 °C.
• 1 exhibits an emission at 366 nm assigned to SO42−SO42− → Cd transfer.

A new 3D Cd-triazolate MOF compound [Cd(Hatrz) (SO4)] (1) (Hatrz = 3-amino-1H-1,2,4-triazole) was obtained from in situ decarboxylication of 5-amino-3-carboxyl-1,2,4-triazole (H2atrc) under the hydrothermal reaction of CdSO4 with H2atrc. Compound 1 features itself a Hatrz-supporting 3D architecture based on the connection of inorganic [CdSO4] layers with Hatrz spacers. Cd(II) atom, SO42−SO42− and Hatrz dummied as 6-, 4- and 2-connected nodes respectively, compound 1 can be simplified to a (2,4,6)-connected {44.62.88.12}{44.62}{8} topological network. The thermal stability of 1 is up to ca. 402 °C, and the fluorescence of 1 shows an emission at 366 nm, originating from SO42−SO42− → Cd transfer. PXRD of compound 1 confirms the phase purity of the bulk sample. FT-IR spectrum of 1 is in accord with the structure analysis.

Hatrz-supporting 3D architecture [Cd(Hatrz) (SO4)] (1) (Hatrz = 3-amino-1H-1,2,4-triazole) was obtained from in situ decarboxylication of 5-amino-3-carboxyl-1,2,4-triazole, which is a (2,4,6)-connected {44.62.88.12}{44.62}{8} net and characterized by TG and fluorescence.Figure optionsDownload as PowerPoint slide
