<p>Post-synthetic
modification (PSM) of metal–organic frameworks (MOFs) is an important strategy
for accessing MOF analogues that cannot be easily synthesized <i>de novo</i>.
In this work, the rare-earth (RE) cluster-based MOF, Y-CU-10, with <b>shp</b>
topology was modified through transmetallation using a series of RE ions,
including: La(III), Nd(III), Eu(III), Tb(III), Er(III), Tm(III), and Yb(III).
In all cases, metal-exchange higher than 70 % was observed, with reproducible
results. All transmetallated materials were fully characterized and compared to
the parent MOF, Y-CU-10, in regards to crystallinity, surface area, and
morphology. Additionally, single-crystal X-ray diffraction (SCXRD) measurements
were performed to provide further evidence of transmetallation occurring in the
nonanuclear cluster nodes of the MOF. </p>
