FeGa2(PO4)3 is quartz (alpha)-derived structured and crystallizes in the monoclinic C2 space group. Fe(1) is bonded to two equivalent O(3) and two equivalent O(6) atoms to form FeO4 tetrahedra that share corners with four equivalent P(2)O4 tetrahedra. Ga(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form GaO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with four equivalent Ga(1)O4 tetrahedra.

There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Ga(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Ga(1) and one P(2) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Fe(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Ga(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Ga(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Fe(1) and one P(2) atom.
