Abstract

A polyoxometalate-based {MnIII3MnIV} single-molecule magnet exhibits a large axial anisotropy (D = −0.86 cm−1) resulting from a near-parallel alignment of Jahn–Teller axes. Its rigorous three-fold symmetry (i.e. rhombicity E → 0) and increased intercluster separation via co-crystallization effectively hamper quantum tunnelling of the magnetization.
