Resonant Quantum Tunneling in a New Tetranuclear Iron(<scp>III</scp>)‐Based Single‐Molecule Magnet

Abstract

Complexing deprotonated trihydromethylethane with iron(III) leads to the formation of a tetranuclear iron cluster (see Figure) with a S = 5 spin ground state and a appreciable magnetic anisotropy. Low-temperature investigations demonstrate single molecule magnet behavior and resonant tunneling within the ground state.
