Abstract: The three-dimensional supramolecular aggregation in the title hybrid material, (C₈H₁₀N₅)[H₂PMo₁₂O₄₀]·2.5CH₃OH·4H₂O, is based on the formation of O-HO, N-HO and O-HN hydrogen bonds, and OO and NO electrostatic interactions (OO = 2.95-3.04 Å and NO = 2.91-3.01 Å). Water and methanol solvent molecules make infinite zigzag belts around the organic cations and Keggin polyoxoanions with a chain sequence H₂OCH₃OHCH₃OHCH₃OHH₂OH₂OCH₃OH. Each symmetry-unique water and methanol molecule forms distinct interactions with the other components in the crystal structure. Five methanol solvent molecules in the crystal lattice have site-occupancy factors of 0.5.
