Structure investigation of fluorinated aluminophosphate ULM-3 Al templated by 3-methylaminopropylamine
چکیده انگلیسی

A single-crystal X-ray diffraction analysis of an open-framework aluminophosphate ULM-3 Al prepared by 3-methylaminopropylamine (MAPA) as structure-directing agent revealed an orthorhombic Pcab symmetry (a=9.9949(4) Å, b=15.8229(7) Å, c=18.1963(5) Å, R=0.0648, Z=8, unit cell formula [Al24P24O96F16·C32H112N16]), which differs from the Pbc21 symmetry of the structural analogue prepared in the presence of 1,4-diaminobutane. The 27Al, 31P, 19F, 13C and 1H NMR investigations, which were performed to study in detail MAPA arrangement inside the framework as well as the interactions of MAPA with the aluminophosphate host, confirmed the crystal symmetry and the proposed hydrogen bonding scheme between the template and the framework.

The aluminophosphate analogue of open-framework gallophosphate ULM-3 was synthesized in the presence of 3-methylaminopropylamine. The Pcab crystal symmetry and hydrogen bonding scheme was determined by single-crystal X-ray diffraction and NMR spectroscopy.Figure optionsDownload as PowerPoint slide
