A new organic superconductor has been synthesized: (BEDT-TTF)4Hg3Cl8 [BEDT-TTF bis(ethylenedithiolo)tetrathiafulvalene]. This material goes superconducting at Tc = 1.8 К at a pressure of 12 kbar. An x-ray structural analysis has been carried out. This conductor exhibits a resistance anisotropy which is exceedingly pronounced for an organic conductor. A phase transition occurs near 40 K.
