Structures and magnetic properties of novel Ln()-based pentanuclear clusters: magnetic refrigeration and single-molecule magnet behavior
Six new and novel polynuclear Ln III 5 clusters, formulated as [Ln 5 (L) 4 (acac) 7 ]·solvents (Ln( iii ) = Sm ( 1 ), Eu ( 2 ), Gd ( 3 ), Tb ( 4 ), Dy ( 5 ) and Ho ( 6 ), Hacac = acetylacetone, and H 2 L = 2-[(2-(hydroxyimino)propanehydrazide)methyl]-5-hydroxymethyl-2-furancarboxylic acid) have been...
