In this HOT article, a detailed study of the impact of a Jahn-Teller distorted Cu(II) ion in the anti-ferromagnetically coupled ring, Cr7Cu, is reported. The Jahn-Teller distortions are identified using spectroscopic techniques and a theoretical characterization is also presented. The problem is important for molecular magnetism as the origin of Jahn-Teller related magnetic anisotropy and consequently the barrier for the spin reversal is single molecular magnets.
