Li3V5(PO4)6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 1-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.09–2.57 Å. In the second Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.09 Å) and two longer (2.39 Å) Li–O bond lengths. There are four inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to five O2- atoms to form VO5 trigonal bipyramids that share corners with five PO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.92–2.05 Å. In the second V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with four VO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 58–60°. There are a spread of V–O bond distances ranging from 1.95–2.10 Å. In the third V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. There are a spread of V–O bond distances ranging from 2.02–2.08 Å. In the fourth V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 60°. There are four shorter (2.02 Å) and two longer (2.18 Å) V–O bond lengths. 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 four equivalent VO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three VO6 octahedra and a cornercorner with one VO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 43–58°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four VO6 octahedra and an edgeedge with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 37–51°. There is two shorter (1.52 Å) and two longer (1.59 Å) P–O bond length. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four VO6 octahedra and an edgeedge with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 43–52°. There is two shorter (1.53 Å) and two longer (1.58 Å) P–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one V3+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one V3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one V3+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one V3+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one V3+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two V3+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two V3+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to one V3+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one V3+, and one P5+ atom.
