Abstract
Superconducting radical cation salts derived from the donor molecule bis(et hylenedithio)tetrathiafulvalene (ET) are an important class of molecular or ganic conductors. Superconducting ET-iodine phases, owing to relatively hig h transition temperatures, are playing a key role in the development of pro totypic devices. Here is reported a novel redox preparation of the organic metal alpha-(ET)(2)I-3, as well as a study of the thermally induced convers ion of this material and the structural characterization and superconductin g properties of the transformation product.
