| Abstract: | The compounds KAg(NO3)2 and RbAg(NO3)2 exhibit similar Raman spectra which are consistent with their crystal structures determined by X-ray diffraction. Polymeric complexes are formed between silver and nitrate ions and the nitrate ions act as both unidentate and bidentate ligands. The compound CsAg(NO3)2 has a different Raman spectrum. The well separated band at 224 cm-1 in the external vibrational region and the unique three-peak profile in the v3 region suggest that there may exist discrete complexes of silver and nitrate ions in the crystal CsAg(NO3)2.The strong interaction which accounts for the nonequivalent sets of nitrate ions in molten AgNO3 appears to exist also in the compounds KAg(NO3)2, RbAg(NO3)2 and CsAg(NO3)2. |
