Notes. Electrosynthesis and resonance-Raman spectrum of phthalocyaninatoiron(II)

Abstract

The electrosynthesis of phthalocyanine complexes [M(pc)] of iron, cobalt, nickel, and copper has been carried out and the method provides a facile, one-stage, room-temperature preparation. The electronic and i.r. spectra have been studied for all four complexes and resonance-Raman data are presented also for [Fe(pc)] dissolved in aniline. Excitation profiles based on the electronic absorption band of [Fe(pc)] at 606 nm suggest that this electronic absorption is a vibronic shoulder on the side of the main electronic (0–0) transition at 668 nm.
