In the first Sn3+ site, Sn3+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Sn–O bond distances ranging from 1.99–2.14 Å. In the second Sn3+ site, Sn3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sn–O bond distances ranging from 2.25–2.69 Å. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent LiO6 octahedra and corners with two equivalent SnO6 octahedra. The corner-sharing octahedra tilt angles range from 27–36°. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one LiO6 octahedra and corners with three equivalent SnO6 octahedra. The corner-sharing octahedra tilt angles range from 15–43°. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one LiO6 octahedra and a cornercorner with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 52–61°. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There is two shorter (1.51 Å) and two longer (1.62 Å) P–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+, one Sn3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Sn3+ and one P5+ atom. In the third O2- site, O2- is bonded to two Li1+, one Sn3+, and one P5+ atom to form a mixture of distorted corner and edge-sharing OLi2SnP trigonal pyramids. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Li1+, one Sn3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sn3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Li1+, one Sn3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, one Sn3+, and one P5+ atom. In the eighth O2- site, O2- is bonded to two Li1+, one Sn3+, and one P5+ atom to form distorted corner-sharing OLi2SnP trigonal pyramids. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+, one Sn3+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted linear geometry to one Sn3+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sn3+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Sn3+, and one P5+ atom.
