Equatorially Coordinated Lanthanide Single Ion Magnets

The
magnetic relaxation dynamics of low-coordinate DyIII and
ErIII complexes, namely three-coordinate ones with
an equatorially coordinated triangle geometry and five-coordinate
ones with a trigonal bipyramidal geometry, have been exploited for
the first time. The three-coordinate Er-based complex is the first
equatorially coordinated mononuclear Er-based single-molecule magnet
(SMM) corroborating that simple models can effectively direct the
design of target SMMs incorporating 4f-elements.
