Crystal structure and magnetic behavior of decamethylferrocenium bis(2-thioxo-1,3-dithiole-4,5-diselenolato)nickelate(III)

The crystal structure of [Fe(Cp∗)2][Ni(dsit)2] consists of layers composed by parallel chains, where side-by-side pairs of cations alternate with dimerized anions, ⋯D+D+(A−A−)D+D+(A−A−)⋯. Short interdimer contacts give rise to a porous 3D network with the donors located in the cavities. The magnetic behavior results from the sum of nearly independent donors with the acceptors network with strong AFM coupled [Ni(dsit)2]22- dimers.
