Studies of anhydrous metal nitrates. III. Vibrational spectra and the nature of nitrato coordination

Abstract

The infrared and Raman spectra of ammonium hexanitratocerate(IV), anhydrous mercury(II) nitrate, and anhydrous cobalt(II) nitrate are reported. The spectrum of (NH₄)₂[Ce(NO₃)₆] is analysed on the basis of the recent detailed structural determination. A similar analysis is then made for Co(NO₃)₂ and Hg(NO₃)₂ the structures of which are not known. The usefulness of vibrational spectra to establish the coordination of the nitrato ligand is examined.
