Di(bis(ethylenedithio)tetrathiafulvalene)triiodide ((BEDT-TTF)/sub 2/I/sub 3/) crystals in the form of distorted hexagon-shaped plates or blocks grown from 1,1,2-trichloroethane and in the form of needles grown from benzonitrile were found to be superconducting at ambient pressure below 1.40 +- 0.02 K. rf penetration depth measurements of the critical temperature and critical field are described. (BEDT-TTF)/sub 2/I/sub 3/ is the first known sulfur-based, ambient pressure organic superconductor.
