A NEW MOLECULAR SUPERCONDUCTOR, (BEDT-TTF)2(I3)1−x(AuI2)x(x<0.02)

Abstract

Abstract A new molecular superconductor based on BEDT-TTF molecule was prepared electrochemically by using the mixed supporting electrolyte, (n-C4H9)4NI3 and (n-C4H8)4NAuI2. The superconducting transition takes place at ambient pressure at 3.6 K. X-Ray diffraction patterns show that the system can be approximately assigned to a pseudo orthorhombic one with the lattice constants of a=10.076(2), b=33.853(5), c=4.964(1) Å.
