Ga3(PO4)4 crystallizes in the cubic I-43m space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent O(2) atoms to form GaO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. All Ga(1)-O(2) bond lengths are 1.85 Å. In the second Ga site, Ga(2) is bonded to four equivalent O(1) atoms to form GaO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. All Ga(2)-O(1) bond lengths are 1.87 Å. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one Ga(1)O4 tetrahedra and corners with two equivalent Ga(2)O4 tetrahedra. The P(1)-O(2) bond length is 1.54 Å. The P(1)-O(3) bond length is 1.48 Å. Both P(1)-O(1) bond lengths are 1.53 Å. There are three inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Ga(1) and one P(1) atom. In the second O site, O(3) is bonded in a single-bond geometry to one P(1) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one Ga(2) and one P(1) atom. Linkers: 24 [O]P([O])([O])=O. Metal clusters: 18 [Ga]. RCSR code: nju. The MOF has largest included sphere 10.69 A, density 1.23 g/cm3, surface area 2691.51 m2/g, accessible volume 0.57 cm3/g
