Synthesis, structure and magnetic properties of a decametallic Ni single-molecule magnet

Ferromagnetic exchange between the ten Ni2+ ions in the complex [Ni-10(tmp)(2)(N-3)(8)(acac)(6)(MeOH)(6)] leads to a spin ground state of S = 10; single crystal M vs. H studies reveal the temperature and sweep rate dependent hysteresis loops expected for a single-molecule magnet.
