Abstract: In the asymmetric unit of the title salt, (C₅H₁₂NO)₆[PMo₁₂O₄₀]₂·5C₅H₁₁NO, there are two independent -Keggin-type [PMo₁₂O₄₀]^3- polyoxidoanions, which show characteristic features with respect to bond lengths and angles. One of the [CH₃CH₂C(=OH)N(CH₃)₂]⁺ cations is hydrogen bonded to the neighboring polyoxidoanion through a C=O-HO_bridge hydrogen bond. The organic molecules and the remaining organic cations form [(C₅H₁₁NO)₂H]⁺ molecule-cation pairs, two of which lie about inversion centers, through O-HO hydrogen bonds.
