MOLECULAR STRUCTURE AND MAGNETIC PROPERTIES OF ACETATO-BRIDGED LANTHANIDE(III) DIMERS

摘要: Structural, magnetic, and EPR studies of diaquatetrakis({mu}-acetato)dicopper(II) have provided important insight into the magnetic interaction phenomenon in polynuclear species involving 3d ions. This compound may be considered at archetype exchange-coupled copper(II) dimers. Until now, no same nature lanthanide(III) ions had been reported, factors determining sign magnitude between are far from being well understood. Herein authors report on synthesis, structure properties two dimers, namely [Ln{sub 2}(CH{sub 3}CO{sub 2}){sub 6-} (phen){sub 2}] with phen = o-phenanthroline Ln Ce (1) Gd (2).
