Synthesis and Characterisation of Heterobimetallic Lanthanoid O‐Based Cluster/Cages

The synthesis of new mono-and bimetallic lanthanoid cluster compounds is reported. The metal-to metal ratios of tetra-and pentanuclear clusters were determined by energy-dispersive X-ray spectroscopy (EDS). The EDS results show that, for an equal proportion of lanthanide salts introduced, different metal-to-metal ratios are achieved in the clusters. This ratio appears to be dependent on the size and electron density of the metal atoms. Studies realized the best conditions to achieve a 1:1 ratio.
