Abstract

In a spin: The mixed-valent (MnIII20-xM-Mn IIx} cage complexes (x = 2-6) have structures corresponding to a fragment of a cubic close-packed lattice (see picture, Mn large sphere, O small sphere). Magnetic studies show for the cage with x = 2 that the ground state has a spin (S) of 19 ± 1 in low field, which increases to about S = 30 at higher fields. The cage is a (Chemical Equation Presented) "single molecule magnet" with a high energy barrier (43 K) to reorientation of the magnetization. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
