GaPO4 crystallizes in the orthorhombic C222_1 space group. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form GaO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Ga(1)O4 tetrahedra. There are two 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 bent 120 degrees geometry to one Ga(1) and one P(1) atom.
