"Metallostar" is a relatively recent term: the oldest publication mentioning metallostars that I was able to find is dated 2000. It defines them as "complexes in which a single branching site bears a number of metallated arms". Something that looks too beautiful to be of any practical use, in fact metallostars appear to be promising MRI contrast agents. The metallostar of today's post, coming from the recent paper in Dalton Transactions, contains a central ruthenium atom and six lanthanoid(III) atoms (Y, Gd or Eu).
