A cobalt(II)-nitronyl nitroxide single chain magnet with record blocking temperature and low coercivity.

Two one-dimensional coordination polymers were synthesized: [M(hfac)2(9-PhentNIT)]n, where MII= Mn (1) or Co (2), hfac- is hexafluoroacetylacetonato and 9-PhentNIT is a new stable nitronyl nitroxide organic radical 2-(9-Phenantrenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (9-PhentNIT). These...
