Popis:	Recently, a conductive coordination compound [Cu(TANC)](F) 0.5 with new radical frameworks was synthesized, where TANC stands for 5,6,11,12-tetraazanaphacene. We have measured the electrical resistivity of [Cu(TANC)](F) 0.5 under high pressures up to 8.0 GPa. At ambient pressure, the temperature dependence of the resistivity shows semiconducting behavior described by a variable range hopping conduction, ρ( T ) ∼exp ( T 0 / T ) η . The value of T 0 increases with increasing pressure up to 6.5 GPa, beyond which it decreases abruptly. The pressure dependence of T 0 is discussed in terms of the increase of the pureness of one-dimensionality and the strength of the random potential due to disordered F - ions.
