Full TextAbstract
The three-dimensional supramolecular aggregation in the title hybrid material, (C8H10N5)[H2PMo12O40]2.5CH3OH4H2O, is based on the formation of O—H O, N—H O and O— H N hydrogen bonds, and O O and N O electrostatic interactions (O O = 2.95–3.04 A ˚ and N O = 2.91–3.01 A ˚ ). Water and methanol solvent molecules make infinite zigzag belts around the organic cations and Keggin polyoxoanions with a chain sequence H2O CH3OH CH3OH CH3OH H2O H2O CH3OH . 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.
