Two {Ln 10 } cages are reported (Ln = Dy or Gd) which feature a nine-metal ring surrounding a central metal site. Magnetic studies show weak anti-ferromagnetic exchange around the nine-metal ring, which should create spin frustration. Two new decametallic lanthanide complexes are reported, that are...

Description
Summary:Two {Ln 10 } cages are reported (Ln = Dy or Gd) which feature a nine-metal ring surrounding a central metal site. Magnetic studies show weak anti-ferromagnetic exchange around the nine-metal ring, which should create spin frustration. Two new decametallic lanthanide complexes are reported, that are large odd-numbered rings with a further central metal site. This type of structure appears to be unprecedented. Magnetic studies show weak exchange interactions between the spin sites for the {Gd 10 } disc.
