A new compound, Al2P2O8F2 [(CH3)(2)CHNH2CH2CH2NH2CH(CH3)(2)] (denoted AlPO-CJ8), with a 1-dimensional fluoroaluminophosphate chain and an Al/P ratio of unity has been synthesized solvothermally by using isopropylamine as an organic additive. It is characterized by X-ray powder diffraction (XRD),inductively coupled plasma (ICP), ion selective electrodes (ISE), and TGA-DTA analyses and structurally determined by single-crystal X-ray diffraction analysis. AlPO-CJ8 crystallizes in the triclinic space group P (1) over bar with a = 5.0306(8) Angstrom, b = 9.3626(15) Angstrom, c = 10.6131(17) Angstrom, alpha = 65.949(4)degrees, beta = 88.218(4)degrees, gamma = 77.19 degrees, and Z = 2. Its structure is built up by alternation of tetrahedral PO3 (= O) and AlO3F units to form infinite 1-D Al2P2O8F22- macroanionic chains. The inorganic chains are held together by diprotonated N,N'-diisopropylethylenediamine through H-bonds. The organic species N,N-diisopropylethylenediamine is believed to be formed through solvothermal reaction of the organic additive isopropylamine and the solvent ethylene glycol. The existence of terminal P = O and Al-F bond groups in the 1-D chain indicates that it has potential to further set up higher dimensional networks through condensations.
