Functionalization of polyoxometalates by carboxylato and azido ligands: macromolecular complexes and extended compounds

Polyoxometalate compounds continue to be widely studied due to their relevance in various fields such as catalysis or magnetochemistry. In this article, we will focus on two topics we recently developed, the functionalization of rare earth polyoxometalates by organic ligands, which has led to compounds ranging from magnetic macromolecular complexes to a 3D open- framework system, and the functionalization of first row transition metal substituted polyoxometalates by azido ligands, which has allowed the isolation of complexes exhibiting the largest ferromagnetic exchange couplings observed to date in polyoxometalate chemistry.
