Calix[4]arene-supported rare earth octahedra.

A series of calix[4]arene-supported Ln(6)(III) clusters have been synthesised under facile bench top conditions. The magnetic and structural properties of these clusters are reported, the latter suggesting that the Ln(III)-calix[4]arene moiety may be used for the construction of other assemblies in a manner akin to that for the Mn-III-calix[4]arene analogue.
