Syntheses, structures and magnetic properties of Fe_6 and Fe_（12） ferric wheels

Starting from the same Fe3O（RCO2）6 complex and using a similar synthesis strategy, the Fe6 and Fe12 wheels were obtained by utilizing two designed ligands, 2-amino-2-methyl-1,3-propanediol（L1） and 1,3-propanediol（L2）, respectively. A biological buffer reagent, Bis-Tris（2-[bis-（2-hydroxyethyl）amino]-...

Summary:Starting from the same Fe3O（RCO2）6 complex and using a similar synthesis strategy, the Fe6 and Fe12 wheels were obtained by utilizing two designed ligands, 2-amino-2-methyl-1,3-propanediol（L1） and 1,3-propanediol（L2）, respectively. A biological buffer reagent, Bis-Tris（2-[bis-（2-hydroxyethyl）amino]-2-（hydroxymethyl）propane-1,3-diol） was first introduced in the synthesis of the Fe12 wheel, playing a vital role in adjusting the acidity of reaction environment. Magnetic studies on both Fe6 and Fe12 wheels revealed strong antiferromagnetic coupling between the spins on FeIII ions.
