Synthesis and structure of a 2-D-aluminophosphate Al3P4O16 center dot 3CH(3)CH(2)CH(2)NH(3)

Using n-propylamine as a template, a new two-dimensional aluminophosphate A l3P4O16. 3CH(3)CH(2)CH(2)NH(3), 1 [space group P2(1)/n (no. 14), a = 11.310 (1) Angstrom, b = 14.854(1) Angstrom, c = 14.796(1) Angstrom, beta = 93.64( 1)degrees, Z = 4] is synthesised in an alcoholic system and the structure i s solved using single-crystal X-ray diffraction data. The structure consist s of tetrahedral AlO4 and PO3(=O) which are linked alternatively to form ma croanionic layers parallel to the (10 (1) over bar) plane. The organic cati ons (C3H7NH3+) are located in the interlayer regions and are connected to-t he 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.
