How metal ions link in metal-organic frameworks: dots, rods, sheets, and 3D secondary building units exemplified by a Y(iii ) 4,4′-oxydibenzoate
Journal article, 2025
In the field of metal-organic frameworks, the use of yttrium(iii) cations and the formation of 3D inorganic building units are rather rare. Here we report an yttrium(iii) metal-organic framework based on the V-shaped ditopic linker 4,4 '-oxydibenzoate, oba2-: [Y16(mu-OH2)(mu 3-OH)8(oba)20(dmf)4]7H2O7dmf, 1, which was solvothermally prepared, with single crystal X-ray diffraction revealing an unusual 3D metal secondary building unit. When activated at 200 degrees C, 1 desolvated to form compound 2, [Y16(mu-OH2)(mu 3-OH)8(oba)20]6H2O, retaining the same structure with a 3% shrinkage in unit cell volume.
