Li3Sb(PO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.03–2.22 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share a cornercorner with one SbO6 octahedra, corners with five PO4 tetrahedra, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 80°. There are a spread of Li–O bond distances ranging from 2.02–2.21 Å. In the third Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.05–2.82 Å. Sb3+ is bonded to six O2- atoms to form SbO6 octahedra that share a cornercorner with one LiO5 square pyramid, corners with six PO4 tetrahedra, and an edgeedge with one LiO5 square pyramid. There are a spread of Sb–O bond distances ranging from 2.22–2.40 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent SbO6 octahedra and corners with two equivalent LiO5 square pyramids. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent SbO6 octahedra and corners with three equivalent LiO5 square pyramids. The corner-sharing octahedra tilt angles range from 57–65°. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sb3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Sb3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Sb3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to three Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Sb3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Sb3+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to three Li1+, one Sb3+, and one P5+ atom.
