摘要：

Bis(ethylendithio)tetrathiafulvalene (BEDT-TTF or ET) can be oxidized with Cu(SCN)2 to yield superconducting, microcrystalline kappa-(ET)2Cu(NCS)2. The reaction is achieved either by heating a suspension of the reactants in various organic solvents or by ultrasound agitation at room temperature. The formation of the title compound was established by X-ray diffractograms, FT-IR and ESR spectroscopy. Susceptibility measurements revealed superconducting transition temperatures of 9.5-10 K. The clearly observed Meissner effect suggests superconductivity to be a bulk property of the so-obtained powder samples.
