A new three-dimensional zinc phosphate, Zn3(HPO4)2(OH)(H2O)2, has been prepared hydrothermally by using 1-butyl-3-methylimidazolium bromide (BMIMBr) as template. The structure of the compound was solved by single-crystal X-ray diffraction analysis. Zn3(HPO4)2(OH)(H2O)2 crystallizes in the orthorhombic space group Pbnm with a=5.0340(10)Å, b=10.611(3)Å, c= 18.312(16)Å, α=β=γ=90o, Z=8, and V=978.1(5)Å3. As primary building units in the individual sheet, alternating PO4 tetrahedra with terminal -OH groups and two water molecules, and ZnO4 tetrahedra and ZnO6 are linked together to form elliptical eight-membered rings as well as four-membered rings. For catalytic application, iron metal ion was inserted into its pore by using cation exchange method on epoxidation of 1-hexene. |
