The organic electron-donor molecule ET, 1, has been the current central focus of research in organic superconductors because it forms numerous solid phases with anions, X/sup /minus//, of which the /beta/-(ET)/sub 2/X materials, X = IBr/sub 2//sup /minus//, AuI/sub 2//sup /minus//, and I/sub 3//sup /minus//, are ambient pressure superconductors with T/sub c/'s = 2.8 K, 4.9 K, and 1.5 K (and 8 K at p > 0.5 kbar), respectively. The synthesis of these materials has been summarized in detail in the literature and is discussed in this report. 9 refs., 4 figs., 1 tab.
