    Abstract: A 3:2 salt (BPDT-TTF)â(InIâ)â was obtained by electrocrystallization and its structure was determined by single-crystal x-ray diffraction (triclinic, space group /bar P/1, a = 7.403 (2) /angstrom/, b = 9.170 (2) /angstrom/, c = 25.883 (7) /angstrom/, /alpha/ = 89.29 (2)/degree/, /beta/ = 96.34 (2)/degree/, /gamma/ = 92.83 (2)/degree/, V = 1774.2 (8) /angstrom/³, Z = 1). Analysis of the C/double bond/C and C/emdash/S bond lengths in the PT (i.e., BPDT-TTF) molecules suggest that this salt consists of donor molecules PT in two different oxidation states (i.e., BPDT-TTF/sup +/ and BPDT-TTF/sup 0.5+/). This oxidation assignment is consistent with the authors ESR measurements and band electronic structure calculations. The (BPDT-TTF)â(InIâ)â salt is a semiconductor at room temperature and below, which can be rationalized in terms of electron localization in the stacks of BPDT-TTF/sup +/ cations and the electronic instability associated with the well-nested Fermi surface for the layers of (BPDT-TTF)â/sup +/ dimers. Preliminary x-ray diffraction experiments indicate that (BPDT-TTF)â(T1Iâ)â is isostructural with (BPDT-TTF)â(InIâ)â. 28 refs., 7 figs., 3 tabs.
