Two unique star-like [MnIVMn III2LnIII] clusters: magnetic relaxation phenomena†
Abstract
Employment of H3L2 (=2-(β-naphthalideneamino)-2-hydroxyethyl-1-propanol) in manganese–lanthanide cluster chemistry has led to the isolation of two new isostructural tetrametallic [MnIII2MnIVLnIII] complexes (Ln = Gd, Dy), with the Dy analogue displaying temperature and frequency dependent out-of-phase signals, thus indicating possible single molecule magnetism behaviour.
