Abstract

A new 3D Terbium (III) metal-organic framework has been solvothermally synthesized by using terbium ion as the metal center and 1,1 $^{'}$ ,1 $^{''}$ -(2,4,6-trimethylphenyl-1,3,5-tri) trimethyl tritrium (4-carboxylpyridyl) tribromide (H₃LBr₃) as ligand. The molecular formula is [Tb(H₃LBr₃) (OH)₂](NO₃)●(DMAC)₃. Compound crystallizes in the triclinic system, space group $P - 1$ , with $a = 9.5747 (8)$ , $b = 12.8667 (10)$ , $c = 18.9440 (14)$ Å, $α = 107.619 {(2)}^{\circ}$ , $β = 99.057 {(2)}^{\circ}$ , $γ = 97.615 {(3)}^{\circ}$ , $V = 2156.0 (3)$ Å³, $Z = 2$ , $M_{r} = 1041.85$ , $D_{c} = 1.605$ g/cm³, $μ = 1.717$ mm $^{- 1}$ , $F (000) = 1068$ , $R = 0.0583$ and $w R = 0.1262$ for 7586 observed reflections ( $I > 2 σ$ (I)). Meanwhile, the fluorescence property was also studied. The result shows that the synthesized Tb-MOF displays highly selective sensing of acetone.
