Stringing Oxo-Centered Trinuclear [MnIII ₃O] Units into Single-Chain Magnets with Formate or Azide Linkers

Magnetic strings: Single‐molecule‐magnet‐like [Mn3IIIO] units are strung into two chain compounds along the magnetic easy axis with formate and azide anions, respectively, as bridges (see picture). The enhanced uniaxial anisotropy and intrachain coupling of these two chain compounds mean that they a...

Description
Summary:Magnetic strings: Single‐molecule‐magnet‐like [Mn3IIIO] units are strung into two chain compounds along the magnetic easy axis with formate and azide anions, respectively, as bridges (see picture). The enhanced uniaxial anisotropy and intrachain coupling of these two chain compounds mean that they act as single‐chain magnets with a high energy barrier for magnetization relaxation.
