Abstract
The conditions required for formation of unusual bottlebrush-shaped lanthanoid coordination clusters were investigated. The known clusters are supported by tetrazole-functionalised p-t-butylcalixarenes, and carboxylate co-ligands. It was confirmed that the lighter lanthanoids form mononuclear complexes, and heavier lanthanoids form bottlebrush clusters. Changing the carboxylate co-ligand had little impact on the complexes formed. Altering the structure of the calixarene had a significant impact. When the t-butyl group was replaced with hydrogen or allyl groups, mononuclear complexes formed.
