Series of Isostructural Planar Lanthanide Complexes [LnIII 4(μ3-OH)2(mdeaH)2(piv)8] with Single Molecule Magnet Behavior for the Dy4 Analogue

A series of five isostructural tetranuclear lanthanide complexes of formula [Ln4(μ3-OH)2(mdeaH)2(piv)8], (mdeaH2 = N-methyldiethanolamine; piv = pivalate; Ln = Tb (1), Dy (2), Ho (3), Er (4), and Tm (5)) have been synthesized and characterized. These clusters have a planar “butterfly” Ln4 core. Magn...

Description
Summary:A series of five isostructural tetranuclear lanthanide complexes of formula [Ln4(μ3-OH)2(mdeaH)2(piv)8], (mdeaH2 = N-methyldiethanolamine; piv = pivalate; Ln = Tb (1), Dy (2), Ho (3), Er (4), and Tm (5)) have been synthesized and characterized. These clusters have a planar “butterfly” Ln4 core. Magnetically, the LnIII ions are weakly coupled in all cases; the Dy4 compound 2 shows Single Molecule Magnet (SMM) behavior.
