Ferromagnetism Induced by Azide Bridges

It is now well known that end-on bridging azide ligands mediate the ferromagnetic exchange between paramagnetic centers [177]. Magnetostructural 

The chemistry of polynuclear Co(ll) complexes is quite rich [32,161,181] and has been particularly exploited in the context of molecular magnetism [154, 182], Since this ion can possess up to three unpaired electrons (S = 3/2) and display large single-ion anisotropy, it is a suitable candidate for SMM synthesis. However, only two SMMs of Co(ll) have been reported to date, although the first identified single-chain magnet (SCM) [ 183] also contains Co(II).
