Fig. 1. Temperature dependence of the molar magnetic susceptibility χMT products for 1 in normal cooling mode (orange); in warming mode after LIESST at 5 K (green) and annealed at 75 K (green to red) and then in warming mode (from 10 K) after the annealing process (red); in quench mode and annealed at 80 K (blue to purple) and then in warming mode (from 10 K) after the annealing process (purple).
