The recent achievements of our group in the synthesis of molecular and poly
meric materials combining conductivity and magnetism are presented. These r
esults will be grouped in three main areas: (1) molecular magnetic conducto
rs based upon TTF-type donors and discrete metal complexes and clusters (me
tal halides, metal cyanides, metal oxalates, polyoxometalate clusters,...),
(2) conducting molecular ferromagnets based upon extended magnetic layers
incorporating donors in between the inorganic layers and (3) conducting pol
ymers incorporating magnetic complexes and clusters.
