Roll the Dy's : Two aggregates made up of dysprosium triangles (one example is shown) display a vanishing susceptibility at low temperature, unprecedented in systems comprising an odd number of unpaired electrons. Despite having a near non‐magnetic ground state, behavior typical of a single‐molecule magnet is observed for the thermally populated excited state.
