Tetrakis(1,4-anisidinium) cyclotétraphosphate hexahydrate

E. H. Soumhi, I. Saadoune and A. Driss

Abstract: The asymmetric unit of the title compound, 4C₇H₁₀NO⁺·P₄O₁₂^4-·6H₂O, consists of two 1,4-anisidinium cations, two PO₄ tetrahedra, which form one half of a cyclic P₄O₁₂^4- anion, and three water molecules. The P₄O₁₂^4- anion is disordered around an inversion centre and exhibits two forms, with occupancies of 0.55 and 0.45. Two-dimensional layers of P₄O₁₂ rings connected to water molecules via weak hydrogen bonds run parallel to the bc plane. The organic cations are linked to these inorganic layers only by N-HO hydrogen bonds. The methoxy groups of the organic cations are not involved in significant intermolecular interactions, leading to a two-dimensional structure.
