Abstract

Abstract : An axially highly compressed pentagonal-bipyramidal holmium(iii ) complex shows a record energy barrier for magnetization reversal. Abstract : We report herein three pentagonal-bipyramidal holmium(iii ) complexes sharing the formula [Ho(L)2 (py)5 ][BPh4 ], where L is the alkoxide ligand. For L = (OSi(CH3 )3 ) −, a record energy barrier for magnetization reversal ( U eff = 715(6) K) was revealed, which is due to the pure state transition of m J = |±8〉 → m J = |±7〉 → m J = |±6〉.
