Abstract: In this paper, a new layered aluminophosphate, [Al6P8O32][(C2H5)2NHCH2CH2NH3]2·[C2H5NH2CH2CH2NH2C2H5], was synthesized in the system Al(OPri)3-H3PO4-N,N-diethyl-ethylenediamine-tetraglycol. Its structure was determined by single crystal X-ray diffraction analysis, and further characterized by XRD, ICP, TG and elemental analysis. The title compound crystallizes in monoclinic space group P2(1)/c , with a=0.909 45(2) nm, b=1.464 24(4) nm, c=1.875 72(5) nm, β=102.672(2)° and Z=4. Its structure constructed by the alternation of AlO4 and PO3(=O) units contains the 4,6,8-nets stacked in an ABAB sequence. Two kinds of organic cations, diprotonnated N,N-diethylethylenediamine and its rearranged product N,N′-diethylethylenediamine locate between the adjacent layers. Their co-templating role in the formation of the title compound was also studied in terms of host-guest interaction.
