Abstract

We report electrical and magnetic studies of [NEt4]2[CuII(mnt)2]. This crystal is composed of chains of theplanar [CuII(mnt)2]-2 anions (space group P1 and z = 1) which exhibit only weak magnetic interactions. The material behaves as a semiconductor; from 300-400°K the conductivity increases by six orders of magnitude and the resistivity values above 300°K are comparable to those of some of the better known wide band-gap inorganic semiconductors. In contrast with the behavior of other linear chain systems, at room temperature the conductivity along the chain (σ) is less than that perpendicular to the chain (σ). As the temperature is increase, the anisotropy ratio, σ, becomes greater than unity and increases to 1.6 × 102 at 400°K.
