N2  - Raman spectra of the crystalline polymeric compounds [HgOH]NO3, [Hg3O2](NO3)2, and [Hg3O2](NO3)2,H2O, obtained by hydrolysis of aqueous solutions of mercury(11) nitrate, are reported. For purposes of comparison with [HgOH]NO3, the Raman spectrum of polymeric [HgNH2]Cl is also recorded. The two most significant aspects of the Raman spectra of these hydrolysis products are the dependence of the frequency of the most intense Hg-O stretching mode on the number of mercury atoms bonded to a common oxygen in each compound and the appearance of the nitrate spectrum, which suggests in each case that the ion has symmetry lower than the free ion symmetry (D3h). The spectrum of the solution from which the compound [HgOH]NO3 is isolated is notable for the intensity of the Hg-ONO2 stretching mode and the magnitude of the splitting of the originally degenerate v3 frequency of the free ion.
