Synthesis and characterization of isostructural tetranuclear lanthanide complexes [Ln4(μ3-OH)2(ampdH4)2(piv)10]·4CH3CN (Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er)

A series of seven isostructural lanthanide tetramers of general formula [Ln4(μ3-OH)2(ampdH4)2(piv)10] 4CH3CN, where ampdH4 is 3-amino-3-methylpentane-1,5-diol, piv is pivalate, and Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy (5), Ho (6) and Er (7) have been successfully synthesized and characterized. Magnetic studies on the DyIII analogue show weak intramolecular coupling within the four DyIII ions and Single Molecule Magnet (SMM) behaviour.
