In this paper the authors report the existence of a new ordered structural phase, denoted as ..beta..*-(ET)/sub 2/I/sub 3/, at T = 4.5 K and P = 1.5 kbar. To our knowledge, this is the first structural study of an organic superconductor with the sample at a temperature below the onset temperature for superconductivity. The structure of ..beta..*-(ET)/sub 2/I/sub 3/ derived from the data set obtained with the sample below the superconducting transition temperature, at 4.5 K and 1.5 kbar, is completely ordered but is not isostructural with the ..beta..-phase structures of the I/sub 2/Br/sup -/, AuI/sub 2//sup -/, and IBr/sub 2//sup -/ salts.
