- W2067919549 abstract "Hydrothermal reactions of rare earth oxides with racemic tartaric acid (H{sub 2}tar) yielded 7 rare earth(III) MOFs with general formulas [R{sub 2}(tar){sub 3}(H{sub 2}O){sub 2}]{sub n} (R=Y (1), Sm (4), Eu (5), Tb (6), Dy (7)) and [R{sub 2}(tar){sub 2}(C{sub 2}O{sub 4})(H{sub 2}O){sub 2}]{sub n}{center_dot}4nH{sub 2}O (R=La (2), Nd (3)). X-ray powder diffraction analysis and single-crystal X-ray diffraction analysis reveal that they present two different structural types. MOFs 1, 4, 5, 6 and 7 are isostructural and crystallize in the orthorhombic non-centrosymmetric space group Iba2, and feature unusual fsc-3,4-Iba2 topology. MOFs 2 and 3 are isostructural and crystallize in monoclinic P2{sub 1}/c space group and display rare fsx-4,5-P2{sub 1}/c topology containing hydrophilic channels bounded by triple helical chains along a axis. MOFs 3, 4, 5, 6 and 7 exhibit intense lanthanide characteristic photoluminescence at room temperature. - Graphical Abstract: [R{sub 2}(tar){sub 2}(C{sub 2}O{sub 4})(H{sub 2}O){sub 2}]{sub n}{center_dot}4nH{sub 2}O (R=La (2), Nd (3)) display rare fsx-4,5-P2{sub 1}/c topology containing hydrophilic channels bounded by triple helical chains along a axis. Highlights: Black-Right-Pointing-Pointer Two types of rare earth MOFs were synthesized by hydrothermal conditions. Black-Right-Pointing-Pointer MOFs feature unusual fsc-3,4-Iba2 and rare fsx-4,5-P2{sub 1}/c topology structures. Black-Right-Pointing-Pointer MOFs exhibit intense lanthanide characteristic photoluminescence." @default.
