Using n-propylamine as a template, a new two-dimensional aluminophosphate Al3P4O16·3CH3CH2CH2NH3, 1 [space group P21/n (no. 14), a=11.310(1) Å, b=14.854(1) Å, c=14.796(1) Å, β=93.64(1)°, Z=4] is synthesised in an alcoholic system and the structure is solved using single-crystal X-ray diffraction data. The structure consists of tetrahedral AlO4 and PO3(=O) which are linked alternatively to form macroanionic layers parallel to the (10
) plane. The organic cations (C3H7NH3+) are located in the interlayer regions and are connected to the oxgens of the layers by hydrogen bonding.The 2-D nets of compound 1 are constructed from 4.6.8-nets which resemble the 2-D nets (4.6.8)1(6.8.8)1 in microporous AlPO4-21.
