| Abstract: | The infrared and Raman spectra of NaNi2OH(H2O)(MoO4)2 and NaZn2OH (H2O)(MoO4)2 and their partially deuterated analogues are recorded and analysed on the basis of vibrations of MoO
4
2−
tetrahedra and H2O molecules. The MoO

2−
groups are found to be more distorted in NaNi2OH(H2O)(MoO4)2 than in the other compound. Bands indicating the presence of H3O+ ions are not observed in NaZn2OH(H2O)(MoO4)2 ruling out the possibility of the formulation of NaZn2OHO(MoO3OH)2. Hydrogen bonds of medium strength are present in both the compounds. |
