Dodecanuclear [Mn III6Ln III6] species: synthesis, structures and characterization of magnetic relaxation phenomena†
Abstract
The use of H3L (= 2-(Ī²-naphthalideneamino)-2-hydroxymethyl-1-propanol) in mixed-metal manganeseālanthanide carboxylate cluster chemistry has led to the isolation of two new dodecametallic heteronuclear isostructural [MnIII6LnIII6] complexes (Ln = Gd, Dy), with the Dy analogue displaying temperature and frequency dependent out-of-phase signals suggesting possible single molecule magnetism behaviour.
