Summary:2-Aminopyridinium heptamolybdate trihydrate, (C5H7N2)6Mo7O24 · 3H2O, is the first heptamolybdate with a multifunctional amine aromatic cation. An analysis of the infrared and polarized Raman spectra of the compound is reported. In the crystal, MoO6 octahedra are found to have a strongly distorted structure. The coincidence of the majority of infrared and Raman hands confirms a noncentrosymmetric structure for the Mo7O6-24 anion. Water bands are assigned by observing the corresponding hands in the deuterated compound. Stretching modes of water show hydrogen bonds of varying strengths.
