Lanthanide clusters represent an intriguing area of chemistry for applications based on their luminescence and magnetic properties in sensing, medical diagnostics, and elsewhere.

Scott Dalgarno, Heriot-Watt University, Edinburgh, UK, and colleagues have used a calixarene analogue that does not resemble the common vase or bowl shape to construct an unusual lanthanide cluster with three metal centers. The ligand in question is bis(5-tert-butyl-2-hydroxy-3-hydroxymethyl-phenyl)methane and was used to make three isostructural polynuclear Ln3 chains in which the metal center is one of gadolinium, terbium, or dysprosium. The team found that the Dy analogue has weak ferromagnetism and the class represents a new way to access a large number of novel coordination complexes of the 3d and 3d–4f elements.
