Abstract

We report e.p.r. and resonance Raman spectra, and electrical conductivity for polycrystalline samples of the M(OEP)(I)x, where M = "H2", Ni, Cu; OEP = 1,2,3,4,5,6,7,8-octaethylporphinato; x {precedes above almost equal to} 5.8. These materials are shown by resonance Raman spectrometry to be properly formulated as M(OEP)(I5-)x/5. The electrical conductivities depend strongly on ρ = x/5 and M. In some cases (e.g., Ni(OEP)(I)x, x > 1.4) the ambient temperature polycrystalline conductivities (∼0.03 S cm-1) and the activation energies (0.10 eV) are comparable with those of polycrystalline samples of materials whose single crystal conductivities are ∼500 Sm-1 with a metal-like temperature dependence (dσ/dt < 0).
