X-Ray Absorption Spectroscopy Studies of Ruthenoxane Phthalocyanine Derivative HO-[(Pc)RuO]n-H

Comprehensive EXAFS investigation carried out on ruthenoxane phthalocyanine and on its chemical precursors ruthenium phthalocyanine dimer and ruthenium bis-pyridine phthalocyanine are reported. The distances around the ruthenium atom were obtained by data analysis and confirm the structural models already proposed for the first two compounds and indicate two pyridines axially coordinated to the central metal for the adduct.
