✦ Synopsis

The title compound, (C~2~H~8~N)~3~[HSiMo~12~O~40~], has an α-Keggin heteropolyoxo anion with a central SiO~4~ tetrahedron and three dimethylammonium cations. The asymmetric unit contains one Si atom and one O with site symmetry \overline{3}m, two Mo atoms, seven O atoms, two C atoms and one N atom with site symmetry m, and one Mo and three O atoms in general positions. These cations and anions are linked via N—H...O hydrogen bonds, forming a layer structure.
