N2 - Two imidazolium templated aluminophosphate layers, [N2C3H5]2 [Al3P4O16H] (1) and [N2C3H5] [AlP2O8H2(OH2)2] (2), have been synthesized under solvothermal conditions at 160°C. The effects of P/Al ratio, the amount of organic amine and the type of solvent on the products are investigated. Their structures are characterized by single-crystal X-ray diffraction (XRD), powder XRD, 27Al DOR NMR, 31P MAS NMR and thermal analyses. Both compounds exhibit unusual structure architectures which are different from previously reported [Al3P4O16]3- and [AlP2O8]3- families. Compound 1 crystallizes in the triclinic space group of P1̄ (No. 2) with a = 8.940(2), b = 9.360(2), c = 11.721(2)A, α = 97.10(2), β = 95.10(2), γ = 91.91(2)°, V = 968.4(3)A3 and Z = 2. The structure contains a new macroanionic inorganic sheet characterized by a series of double six-membered ring (D6R), in which Al moieties (including AlO4 and AlO5) and P moieties [including PO4, PO3(= O) and PO2(= O) (OH)] are corner-shared through oxygen in an alternative manner. Compound 2 crystallizes in the monoclinic space group of C2/c (No. 15) with a = 21.854(4), b = 7.188(2), c = 6.990(2)A, β = 103.77(2)°, V = 1063.5(5)A3 and Z = 4. The structure is based on a new two-dimensionally connected inorganic network containing eight-membered rings in which AlO4(OH2)2 and PO2(OH) (= O) units are connected alternatively.
