[(Tp)₈(H₂O)₆Cu^II₆Fe^III₈(CN)₂₄]⁴⁺: A Cyanide‐Bridged Face‐Centered‐Cubic Cluster with Single‐Molecule‐Magnet Behavior

Abstract

A box of magnetic tricks: By using the anionic precursor [(Tp)Fe(CN)3]− (Tp−=hydrotris(pyrazolyl)borate), the title compound, which is a new face-centered-cubic cluster, has been synthesized (see structure; red Fe, turquoise Cu, orange B, gray C, blue N, dark red O). Magnetic studies show that it exhibits single-molecule-magnet behavior with substantial axial magnetic anisotropy (D=−0.16 cm−1).
