In this paper, two new compounds, (1) and (2), have been synthesized by a one pot process at the reflux condition. Both compounds were characterized by infrared and UV-visible spectroscopy techniques, as well as by X-ray diffraction. The compound (1) crystallizes in the monoclinic system with the space group P21/n and the compound (2) crystallizes in the monoclinic system but with the space group P21/c. The structure consists of a non-protonated heptamolybdates polyanions, stabilized by organoammonium groups and water molecules. The cohesion of the three-dimensional structure is ensured by hydrogen bonds between the polyanions, the organoammonium groups, and the water molecules, thereby providing significant stability to the compound.
