Some Unsymmetrical Metal 1,2-Dithiolenes Based on Palladium, Platinum and Gold

The unsymmetrical complexes Pd(dpedt)(dddt), Pt(dpedt)(dddt), Pd(dpedt)(dmit), and Au(dpedt)- (dddt) (where dpedt is diphenyl-ethylenedithiolate, dddt is 5,6-dihydro-1,4-dithin-2,3-dithiolate and dmit is 1,3-dithiol-2-thione-4,5-dithiolate) were prepared and characterized. The study of their chemical and electrochemical behavior showed that they are stable in air and could be candidate materials for fabrication of field-effect transistors and other devices.
