La3SnGa5O14 crystallizes in the trigonal P321 space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(3) and three equivalent O(2) atoms to form corner-sharing GaO4 tetrahedra. In the second Ga site, Ga(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form GaO4 tetrahedra that share corners with two equivalent Sn(1)O6 octahedra and corners with two equivalent Ga(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 66°. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Ga(2)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one La(1), one Ga(2), and one Sn(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent La(1), one Ga(1), and one Ga(2) atom. In the third O site, O(3) is bonded to three equivalent La(1) and one Ga(1) atom to form corner-sharing OLa3Ga tetrahedra.
