文摘
Co(II) complexes of aminotrisphenolate ((ArO)3N3鈥?/sup>) ligands can be prepared straightforwardly in high yield. X-ray analysis reveals these complexes to comprise of two different hemispheres, one containing an anionic Co((ArO)3N)鈭?/sup> and the other a cationic (ArO)3NH+ unit, which are associated through hydrogen bonding. These Co(II) complexes can be easily converted into their Co(III) analogues in air in the presence of suitable bases such as dimethylaminopyridine and 2,2鈥?bipyridine, and the structural features and magnetic properties of these latter compounds are also reported.
