Ga2P3O11 crystallizes in the orthorhombic Pbcn space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(1), one O(3), one O(4), and one O(6) atom to form GaO4 tetrahedra that share  a cornercorner with one P(3)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, and corners with two equivalent P(2)O4 tetrahedra. The Ga(1)-O(1) bond length is 1.82 Å. The Ga(1)-O(3) bond length is 1.82 Å. The Ga(1)-O(4) bond length is 1.82 Å. The Ga(1)-O(6) bond length is 1.83 Å. In the second Ga site, Ga(2) is bonded to one O(11), one O(2), one O(5), one O(7), and one O(8) atom to form GaO5 square pyramids that share corners with two equivalent P(2)O4 tetrahedra and corners with three equivalent P(3)O4 tetrahedra.

There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(10), one O(9), and two equivalent O(3) atoms to form distorted PO4 tetrahedra that share corners with two equivalent Ga(1)O4 tetrahedra and  an edgeedge with one P(1)O4 tetrahedra. The P(1)-O(10) bond length is 1.54 Å. The P(1)-O(9) bond length is 1.54 Å. There is one shorter (1.50 Å) and one longer (1.53 Å) P(1)-O(3) bond length. In the second P site, P(2) is bonded to one O(11), one O(4), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Ga(2)O5 square pyramids and corners with two equivalent Ga(1)O4 tetrahedra. The P(2)-O(11) bond length is 1.49 Å. The P(2)-O(4) bond length is 1.54 Å. The P(2)-O(6) bond length is 1.54 Å. The P(2)-O(7) bond length is 1.52 Å. In the third P site, P(3) is bonded to one O(1), one O(2), one O(5), and one O(8) atom to form PO4 tetrahedra that share corners with three equivalent Ga(2)O5 square pyramids and  a cornercorner with one Ga(1)O4 tetrahedra. The P(3)-O(1) bond length is 1.56 Å. The P(3)-O(2) bond length is 1.51 Å. The P(3)-O(5) bond length is 1.55 Å. The P(3)-O(8) bond length is 1.54 Å. There are eleven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ga(1) and one P(3) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ga(2) and one P(3) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ga(1) and two equivalent P(1) atoms. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Ga(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Ga(2) and one P(3) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Ga(1) and one P(2) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Ga(2) and one P(2) atom.
