  • Synthesis and structure determination of a chain-like aluminophosphate obtained with 1,2-diaminopropane as the structure-directing agent
    Rajić, Nevenka ...
    Colorless plate-like crystals (AlPO-1,2DAP) crystallize from a clear `AlPO4-1,2-diaminopropaneć reaction system. The results of elemental, thermal and FTIR analyses give the following chemical ... formulaČ (NH4+)(1,2-H2DAP)2+(AlP2O8)3-, confirmed also by single crystal structure determination. The X-ray diffraction data collected at 150 K reveal the space group Pc21n with a=8.2788(2), b=16.7882(3), c=8.6608(2) Å, and V=1203.73(5) Å3. The AlPO-1,2DAP has a chain structure related to the aluminophosphate AlPO-enA structure. Two occluded cations, NH4+ and doubly protonated diamine, balance the negative charge and interact with the chain oxygen atoms via hydrogen bond network.
