title: Mono- and Mixed-Valence Tetrathiafulvalene Semiconductors (TTF)BiI4and (TTF)4BiI6with 1D and 0D Bismuth-Iodide Networks.
abstract: Two new compounds containing tetrathiafulvalene (TTF) cations with extended and discrete anions based on Bi and I are reported. The compound (TTF)BiI4comprises [BiI2I4/2]-chains of edge-shared octahedra that are interspersed with stacks of TTF+•. The compound (TTF)4BiI6has mixed-valence stacks of TTF and TTF+•and discrete molecules of TTF+•separated by discrete [BiI6]-3anions. The optical and electrical transport properties of these compounds are reported. Due to the mixed-valence stacks of TTF, (TTF)4BiI6is the significantly better electrical conductor than (TTF)BiI4, despite the discrete nature of the inorganic moiety.
