Al2(PO6)3PO4 is Indium-derived structured and crystallizes in the trigonal R3 space group. The structure is zero-dimensional and consists of three phosphoric acid molecules and three Al2(PO6)3 clusters. In each Al2(PO6)3 cluster, there are two inequivalent Al sites. In the first Al site, Al(1) is bonded to three equivalent O(1) and three equivalent O(7) atoms to form AlO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra. In the second Al site, Al(2) is bonded to three equivalent O(2) and three equivalent O(8) atoms to form AlO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share  a cornercorner with one Al(1)O6 octahedra and  a cornercorner with one Al(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 26-32°. There are six inequivalent O sites. In the first O site, O(7) is bonded in a single-bond geometry to one Al(1) atom. In the second O site, O(8) is bonded in a single-bond geometry to one Al(2) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one Al(1) and one P(1) atom. In the fourth O site, O(2) is bonded in a bent 150 degrees geometry to one Al(2) and one P(1) atom. In the fifth O site, O(3) is bonded in a single-bond geometry to one P(1) atom. In the sixth O site, O(4) is bonded in a single-bond geometry to one P(1) atom.
