Abstract

That a metal ion is not required for high electrical conductivity is unequivocally demonstrated by structural, charge transport, optical, and magnetic characterization of the simplest phthalocyanine "molecular metal" H₂(Pc)I. The crystal structure consists of staggered H₂(Pc)^+0.33 units stacked at 3.251(3) Å intervals and parallel chains of I^-₃ counterions. At 300 K, σ_{{norm of matrix}} = 700 Ω^-1 cm^-1 and σ_{{norm of matrix}} σ⊥ > 500. At 15 K, σ_∼ reaches a maximum of ca. 4000 Ω^-1 cm^-1 and falls only to ca. 3500 Ω^{-1{norm of matrix}} cm^-1 at 1.5 K. Analysis of single crystal polarized specular reflectance data (ir to uv) yields ω_p = 6360(30) cm^-1 and a tight-binding bandwidth of 1.3(1) eV. The magnetic susceptibility is Pauli-like (X_S = 2.21(5) × 10^-4 emu mol^-1) except for a small, sample dependent Curie component.
