Abstract

The structure, electrical, magnetic, and spectroscopic characteristics of the novel molecular metal tetrabenzoporphyrin iodide (H2(tbp)I) as well as that of nickeltetrabenzpoprphyrin (Ni(tbp)I) were described. Single-crystal reflectance spectroscopy, electrical conductivity, magnetic susceptibility, and electron paramagnetic resonance were utilized. Data revealed that H2(tbp)I and Ni(tbp)I have the same EPR values. The electrical conductivity as well as the Curie constant for Ni(tbp)I were higher than that of H2(tbp)I secondary to the crystal defects and organic impurities.
