LiGaPO5 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(5), and two equivalent O(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a square co-planar geometry to two equivalent O(3) and two equivalent O(5) atoms. In the second Ga site, Ga(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form GaO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and edges with two equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share  a cornercorner with one Ga(2)O6 octahedra and  an edgeedge with one Ga(2)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Ga(2), and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Ga(2), and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Li(1), one Ga(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Ga(2) and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Li(1) and one Ga(1) atom.
