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