Poly[propane‐1,3‐diammonium [tetra‐μ3‐oxo‐hexaoxotrimolybdenum(VI)] dihydrate]

The crystal structure of the title compound, {(C₃H₁₂N₂)Mo₃O₁₀]·2H₂O}_n, is composed of Mo₃O₁₀]²⁻ anionic chains, propane‐1,3‐diammonium cations and solvent water molecules. The Mo₃O₁₀]²⁻ chain is constructed from edge‐sharing MoO₆ octahedra. The protonated propane‐1,3‐diamine cations and solvent water molecules are located between the chains and are linked to the O atoms of the inorganic chains by hydrogen bonds.
