A new two-dimensional aluminium phosphate,
[BuNH3]3[Al3P4O16
], has been synthesized under solvothermal conditions at 453 K
using butylamine as template. The structure, solved using single-crystal
X-ray diffraction data measured at 200 K [trigonal, space group
P, a = 13.158(2),
c = 9.633(2) Å,
U = 1444.4 Å3,
Z = 2], consists of AAAA-stacked
[Al3P4O16]3- layers
containing 12-membered rings of alternating AlO4 and
PO4 tetrahedra. Disordered butylammonium cations lie between
the layers with their hydrophobic tails pointing into the channels
bounded by the 12-membered rings.
