Abstract

High-temperature electrocrystallization techniques afford (Ni(Pc) (C10₄)_y crystals in the stoichiometry range y ≈ 0.39-0.47. The 300 K crystal structure of Ni(Pc)(C10₄)_0.42 consists of stacks of Ni(Pc)^+0.42 units and disordered, off-axis C10₄ ions. At lower temperature, there is diffractometric evidence for anion ordering. Variable-temperature conductivity data exhibit discontinuous behavior below ca. 150 K which may reflect the anion ordering. Thermoelectric power and optical reflectivity data are characteristic of a low-dimensional molecular metal and are also in accord with sample-dependent y values. Both measurements yield a tight-binding bandwidth of ca. 1.5(1) eV.
