Further structural information on the intra- and interunit contacts in dimeric ruthenium phthalocyanine
Previous EXAFS and further LAXS studies fully confirm that solid amorphous ruthenium phthalocyanine, as obtained from its DMSO, pyridine, and isoquinoline adducts, is dimeric with dimers chained to form aggregates of formula [(PcRu)(2)](n) (average n = 6) and with short intradimer Ru-Ru (2.40 Angstrom) and long interdimer (4.30-4.40 Angstrom) bond distances, in contrast with recent different EXAFS findings (very short Ru-Ru interdimer contacts, 3.52 Angstrom) and an associated structural model.
