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 ωp = 6360(30) cm-1 and a tight-binding bandwidth of 1.3(1) eV. The magnetic susceptibility is Pauli-like (XS = 2.21(5) × 10-4 emu mol-1) except for a small, sample dependent Curie component.
