New dithiothiophene complexes for conducting and magnetic materials

New Ni and Au complexes with 2,3-dihydro-5,6-thiophenedithiolate (dtpdt) 2, 3-thiophenedithiolate (alpha -tpdt), and 3,4-thiophenedithiolate (tpdt) hav e been prepared and characterised. Their ability to be used as building blo cks for novel conducting and magnetic materials is demonstrated by differen t new compounds, the most remarkable being Au(alpha -tpdt)(2), a neutral co mplex exhibiting metallic properties, several magnetic materials were obtai ned as salts with decamethyl metallocene cations. The magnetic field/temper ature phase diagram of [Fe(Cp*)(2)][Ni(alpha -tpdt)(2)] is presented.
