Abstract
Chromium lanthanide heterometallic wheel complexes {Cr8Ln8} (Ln=Gd, Dy and Y) with alternating metal centres are presented. Quantum Monte Carlo simulations reveal antiferromagnetic exchange-coupling constants with an average of 2.1 K within the {Cr8Gd8} wheel, which leads to a large ground spin state (ST=16) that is confirmed by magnetization studies up to 20 Tesla. The {Cr8Dy8} wheel is a single-molecule magnet.
