An Organoytterbium(III) Complex Exhibiting Field-Induced Single-Ion-Magnet Behavior

We present a new mononuclear half-sandwich complex, [Cp*Yb (DAD) (THF)]center dot C7H8 (1), based on a paramagnetic YbITI ion coordinated by diamagnetic Cp* and enediamido[2,6-Me(2)C6H(3)NCH= CHNC6H3Me2-2,6]2-(DAD) ligands exhibiting fieldinduced single-ion-magnet behavior.
