The organic conductor, (TTF) (SCN)0.57, is a quasi-one-dimensional non-stoichiometric compound, which crystallizes in a tetragonal system having a P42/mnm space group. The lattice constants are a=11.154 (3) and c=3.607 (2) Å. TTF molecules form segregate eclipsed stacks with thiocyanate ions occupying the channels between the stacks. The intermolecular distance between adjacent TTF molecules is 3.607 Å. The room-temperature electrical conductivity is 85–310 (Ω cm)−1. A series of resistance jumps are observed in the temperature-dependent resistivity curves.
