abstract = {A three-dimensional heterobimetallic porous structure
with the formula {[Y3.5Tb1.5L6(OH)3(H2O)1.5 (DMF)1.5]n·
1.5H2O·DMF}n (L = 3-amino-4-hydroxybenzoate) (Y/Tb-MOF)
has been synthesized and characterized by single crystal and
powder X-ray diffraction, scanning electron microscopy with energy
dispersive X-ray spectroscopy (SEM-EDX), inductively coupled
plasma mass spectrometry (ICP-MS), electrophoretic mobility, and
Fourier transform infrared (FTIR) spectroscopy. The structure
presents two metal environments: a bioaugmented isosceles wedge
(mm2) MO8 and a tricapped trigonal prism (−6m2) MN3O6.
These configurations facilitate the creation of channels with a
diameter of 10.7 Å, enabling its utilization as an active catalyst
where the heterobimetallic nature of the assembly will be explored. This mixed-metal metal−organic framework has been tested in
the cycloaddition of epoxides with carbon dioxide as well as in the cyanosilylation and hydroboration reactions of carbonylic
substrates. Additionally, a monometallic Tb-MOF analogue has been synthesized for comparative evaluation of their catalytic
performances. Both the mixed metal and monometallic variants exhibit outstanding activity in the cyanosilylation and hydroboration
of carbonyls and in the synthesis of carbonates under CO2 pressure. However, only the latter exhibits high recyclability.},
