Abstract: The title polyoxometalate-based organic-inorganic hybrid compound, (C₅H₁₀NO₂)₅[BW₁₂O₄₀]·3H₂O, consists of one -Keggin-type [BW₁₂O₄₀]^5- polyoxoanion, five crystallographically independent L-prolinium cations and three uncoordinated water molecules. The polyoxoanion shows characteristic features with respect to bond lengths and angles. Several N-HO and O-HO hydrogen bonds between the organic cations, inorganic anions and crystal water molecules lead to a three-dimensional supramolecular structure.
