We prepared new π-d magnetic conductors using the TTF-BTA hybrid molecules 1 and transition metal complexes M(hfac)_2 (M=Cu, Co, Ni, Mn) to realize magnetic interactions between the π-conduction electrons and the localized d-spins of the transition metals. We cleared the crystal structure and physical properties of the 1_2M(hfac)_2 (M=Cu, Co, Ni, Mn) complexes. Furthermore, we also prepared a cation radical salts based on new transition metal complex, 1_2Cu(ReO_4)_2 and cleared its crystal structure and magnetic/conducting properties.
