Lanthanoid 'bottlebrush' clusters: remarkably elongated metal-oxo core structures with controllable lengths
journal contribution
posted on 2023-05-20, 08:04 authored by Dalessio, D, Sobolev, AN, Skelton, BW, Rebecca FullerRebecca Fuller, Woodward, RC, Lengkeek, NA, Fraser, BH, Massi, M, Ogden, MILarge metal–oxo clusters consistently assume spherical or regular polyhedral morphologies rather than high-aspect-ratio structures. Access to elongated core structures has now been achieved by the reaction of lanthanoid salts with a tetrazole-functionalized calixarene in the presence of a simple carboxylate co-ligand. The resulting Ln19 and Ln12 clusters are constructed from apex-fused Ln5O6 trigonal bipyramids and are formed consistently under a range of reaction conditions and reagent ratios. Altering the carboxylate co-ligand structure reliably controls the cluster length, giving access to a new class of rod-like clusters of variable length.
