Reaction of dinitrogen oxide with Pentaammineaquaruthenium(II) and isolation of Pentaammine(dinitrogen oxide)ruthenium(II) complexes

The reaction between dinitrogen oxide and Ru(NH3)5OH22+ to form the dinitrogen complexes of pentaammineruthenium(II) was investigated. At high pressures of N2O the Br, I, BF4 and PF6 salts of Ru(NH3)5N2O2+ were isolated. The compounds were characterized and their aqueous chemistry compared with that of the corresponding salts of Ru(NH3)OH22+ whose preparation and characterization are also reported here. The infrared spectra and X-ray powder patterns of the dinitrogen oxide complexes are reported.
