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 (H(2)atrc) under the hydro-thermal reaction of CdSO4 with H(2)atrc. Compound 1 features itself a Hatrz-supporting 3D architecture based on the connection of inorganic [CdSO4] layers with Hatrz spacers. Cd(II) atom, SO42- and Hatrz dummied as 6-, 4- and 2-connected nodes respectively, compound 1 can be simplified to a (2,4,6)-connected {4(4).6(2).8(8).12}(4(4).6(2)}{8} topological network. The thermal stability of 1 is up to ca. 402 degrees C, and the fluorescence of 1 shows an emission at 366 nm, originating from 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.
