Lanthanoid “bottlebrush” clusters: remarkably elongated metal–oxo core structures with controllable lengths. Journal of the American Chemical Society, 136(43), 15122-15125. doi:10.1021/ja506677h
Abstract: Large 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. © 2014 American Chemical Society
