Abstract

A new set of wheels: Substituting a chromium ion in [Cr8F8(O2CCMe3)16] with one of a number of alternative transition metals has yielded an unprecedented family of heterometallic wheel complexes (see picture), supported at their centers by secondary ammonium ions. Both 3d (Mn, Fe, Co, Ni) and 4d (Cd) metals have been employed to produce such structures, the magnetic and spectroscopic properties of which are discussed.
