摘要: Abstract By using the hydrothermal method, a new large-pore three dimensional aluminophosphate Al9(PO)12(C24H81N16)·17H2O has been synthesized. The compound crystallizes in cubic space group I-43m with a=16.7963(13) A, V=4738.5(6) A3, and Z=2. P/Al ratio of this is 4:3 structure consists Al-centered P-centered tetrahedra which all AlO4 vertices PO4 corners are shared. framework contains unique 12-membered ring channels, intersect each other windows dimensions, almost spherical cavities, water amine ions located. window containing P=O groups selectively interacts 4-(2-aminoethyl)diethylenetriamine by effect recognition condition. could exist up to 260°C. At higher temperature, was decomposed released, transferred into amorphous phase. component Al can be partly substituted elements, such as Sn, Zn, Mg, Co, Mn, Cd, charge adjusted.
