Vibrational interpretation of the structure of Co(II), VO2+ and Pb(II) naphthalocyanine complexes

Abstract

The FT-IR and Raman spectra for the solid naphthalocyanine (H2Nc) and their Co(II), VO2+ and Pb(II) complexes were registered, and a band assignment was proposed. On this basis, the structure of the complexes was inferred: The Co(II) and VO2+ complexes are deformed macrocycles, and the Pb ion is out of the plane of the Nc fragment.
