Ga3P2O12F crystallizes in the tetragonal P4_2/ncm space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form GaO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and edges with two equivalent Ga(2)O5F octahedra. Both Ga(1)-O(3) bond lengths are 1.94 Å. All Ga(1)-O(2) bond lengths are 1.95 Å. In the second Ga site, Ga(2) is bonded to one O(4), two equivalent O(1), two equivalent O(2), and one F(1) atom to form GaO5F octahedra that share  a cornercorner with one Ga(2)O5F octahedra, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. The Ga(2)-O(4) bond length is 1.94 Å. Both Ga(2)-O(1) bond lengths are 1.89 Å. Both Ga(2)-O(2) bond lengths are 1.99 Å. The Ga(2)-F(1) bond length is 2.01 Å. P(1) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one Ga(1)O6 octahedra and corners with three equivalent Ga(2)O5F octahedra. The corner-sharing octahedral tilt angles range from 39-48°. The P(1)-O(3) bond length is 1.56 Å. The P(1)-O(4) bond length is 1.52 Å. Both P(1)-O(1) bond lengths are 1.52 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ga(2) and one P(1) atom. In the second O site, O(2) is bonded in a water-like geometry to one Ga(1) and one Ga(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Ga(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Ga(2) and one P(1) atom. F(1) is bonded in a bent 120 degrees geometry to two equivalent Ga(2) atoms. Linkers: 8 [O]P([O])([O])=O. Metal clusters: 12 [Ga]. The MOF has largest included sphere 4.03 A, density 2.30 g/cm3, surface area 2075.42 m2/g, accessible volume 0.17 cm3/g
