A complex sequence of ferro- and antiferromagnetic interactions occurs in the compound [Ni(N,N′-dmen)(μ-N3)2] (N,N′-dmen [DOUBLE BOND] N,N′-dimethylethylenediamine), which exists as a one-dimensional chain in the solid state (shown below; C atoms of the amine ligands are omitted). The magnetic behavior of this unusual spin system has been analyzed in detail.
