The electrical resistivity of an organic metal, (DMDCNQI)2Cu (DMDCNQI: 2,5-dimethyl-N,N′-dicyanoquinonediimine) is measured under pressure. Though this compound retains a metallic state down to 1.5 K at ambient pressure, a metal semiconductor transition appears above 4.5 kbar, and the transition temperature increases with an increase in pressure. On the analogy of the related compounds, this transition is attributed to a kind of one-dimensional instability.
