Abstract: The title compound, catena-poly[[N-methylpropane-1,3-diaminium [-phosphato-(-hydrogen phosphato)(-dihydrogen phosphato)dizincate(II)]], {(C₄H₁₄N₂)[Zn₂(PO₄)(HPO₄)(H₂PO₄)]}_n, consists of macroanionic [Zn₂(PO₄)(HPO₄)(H₂PO₄)]^2- layers and intercalated (C₄H₁₂N₂)²⁺ cations. The layers are built up from ZnO₄ and PO₄/HPO₄/H₂PO₄ tetrahedra that result in small channels of approximate diameter 3.7  Å within the layers. Framework-to-framework O-HO and template-to-framework N-HO hydrogen bonds are important in stabilizing the structure.
