Abstract

Electrocrystallisation of a TTF tertiary amide derivative, that is EDT-TTF-CONMe2, affords a stoichiometric 1 : 1 salt with AuBr2−, τ-(EDT-TTF-CONMe2)(AuBr2)·(TCE)0.5, characterised by a hybrid organic–inorganic layer, with AuBr2− anions interspersed between perpendicular cation radicals. This original structure avoids the strong dimerisation gap usually observed in 1 : 1 salts and allows for a strong two-dimensional band dispersion and the absence of gap. The semi conducting behaviour with a high σRT value (0.025 S cm−1) indicates a Mott–Hubbard behaviour.
