Rare‐Earth Metal Oxo/Hydroxo Clusters – Synthesis, Structures, and Applications

Multinuclear rare‐earth metal coordination clusters bridged by oxo/hydroxo units have emerged from being lab curiosities to become a readily accessible class of compounds. New synthetic strategies for accessing these compounds on reasonable scales have been established. Clusters of different sizes have been investigated in terms of their magnetic and photophysical properties. Some preliminary biological applications have also been established.
