  abstract: The decomposition of the {Ru(NH(,3))(,6)}('3+) complex in both X- and Y-type zeolites was investigated using several techniques including EPR spectroscopy, infrared spectroscopy, and Electron Spectroscopy for Chemical Analysis (ESCA). Following dehydration of a Ru(NH(,3))(,6)('3+) Y zeolite sample at 300(DEGREES)C, a mixture of oxidation states was present. Although a significant portion of ruthenium was reduced, some residual Ru3+ ions were still present. The Ru3+ ions in zeolite Y following dehydration under vacuum at 300 (DEGREES)C form complexes with CO and O2 which have well-resolved EPR spectra. Addition of CO at 25 (DEGREES)C resulted in the formation of a Ru3+ monocarbonyl complex or polycarbonyl complex, depending on the partial pressure of CO. The monocarbonyl complex was characterized by g=2.0600 and g11= 1.9871, whereas the polycarbonyl was characterized by g1= 2.0593, g2= 2.0471, and g3= 1.9970. Hyperfine coupling for 13O and the two ruthenium isotopes, 99Ru and 101Ru, indicates that the unpaired electron is primarily localized (ca. 70%) on the metal ion.
