Magnetic cage : Simple cobalt(II) diketonates react with triols under solvothermal conditions to give a family of compounds based on supertetrahedral cage structures: a regular and a distorted {Co II 10 } species, and a bi‐supertetrahedral {Co II 19 } species. Magnetic studies show unusual properties, such as nonvanishing magnetization below 12 K, which until now have only been detected in a family of {Ni 10 } clusters.
