Nitrato-complexes of iridium. Part 2. M2[Ir(NO3)6](M = K, Rb, or Cs)
Abstract
Potassium, rubidium, and caesium hexanitratoiridate(IV) salts have been prepared by reactions of the corresponding hexabromoiridate(IV) compounds with dinitrogen pentaoxide. Solution properties, vibrational spectra, magnetic properties, and X-ray powder diffraction data are reported and the behaviour of the potassium salt in acetonitrile and 100% nitric acid solutions has been investigated by electronic spectroscopy.
