New dithiothiophene complexes for conducting and magnetic materials

abstract

New Ni and Au complexes with 2,3-dihydro-5,6-thiophenedithiolate (dtpdt) 2,3-thiophenedithiolate (alpha -tpdt), and 3,4-thiophenedithiolate (tpdt) have been prepared and characterised. Their ability to be used as building blocks for novel conducting and magnetic materials is demonstrated by different new compounds, the most remarkable being Au(alpha -tpdt)(2), a neutral complex exhibiting metallic properties, several magnetic materials were obtained as salts with decamethyl metallocene cations. The magnetic field/temperature phase diagram of [Fe(Cp*)(2)][Ni(alpha -tpdt)(2)] is presented.
