摘要：

(Figure Presented) Magnetic strings: Single-molecule-magnet-like [Mn 3IIIO] 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. © 2007 Wiley-VCH Verlag GmbH & Co.
