Abstract
A new open-framework zinc phosphate, Zn3PO4 (HPO4)3 · C6N3 H18 (denoted FJ-11), was synthesized under solvothermal conditions in the presence of 1-(2-aminoethyl)piperazine as structure-directing agent. Its structure was determined by single-crystal X-ray diffraction and further characterized by FTIR, elemental analysis, ICP analysis, powder X-ray diffraction and thermogravimetric analysis. The compound crystallized in the triclinic space group, P-1, with a = 8.2807(2) Å, b = 9.13750(10) Å, c = 13.3463(2) Å, α = 83.7700(10)°, β = 84.4460(10)°, γ = 78.0250(10)°, V = 979.17(3) Å3, Z = 2. The structure consists of ZnO4, PO4 and HPO4 tetrahedra with shared corners, forming intersecting three-dimensional channels. The triply protonated 1-(2-aminoethyl)piperazine molecules reside in the large 16-ring channels and interact with the inorganic framework by extensive hydrogen bonds.
