description: LiTi3P3O13 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with five TiO6 octahedra, corners with three equivalent PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–60°. There are a spread of Li–O bond distances ranging from 1.95–2.47 Å. There are three inequivalent Ti+3.33+ sites. In the first Ti+3.33+ site, Ti+3.33+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with three equivalent LiO5 square pyramids, corners with three PO4 tetrahedra, a cornercorner with one TiO5 trigonal bipyramid, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of Ti–O bond distances ranging from 1.84–2.24 Å. In the second Ti+3.33+ site, Ti+3.33+ is bonded to five O2- atoms to form TiO5 trigonal bipyramids that share a cornercorner with one TiO6 octahedra and corners with five PO4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ti–O bond distances ranging from 1.84–2.01 Å. In the third Ti+3.33+ site, Ti+3.33+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent LiO5 square pyramids, corners with four PO4 tetrahedra, and edges with two equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of Ti–O bond distances ranging from 2.04–2.16 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one TiO6 octahedra and corners with three equivalent TiO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 28°. There is three shorter (1.53 Å) and one longer (1.58 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four TiO6 octahedra, a cornercorner with one TiO5 trigonal bipyramid, and an edgeedge with one LiO5 square pyramid. The corner-sharing octahedra tilt angles range from 42–53°. There is three shorter (1.54 Å) and one longer (1.58 Å) P–O bond length. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent TiO6 octahedra, corners with three equivalent LiO5 square pyramids, a cornercorner with one TiO5 trigonal bipyramid, and an edgeedge with one TiO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ti+3.33+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Ti+3.33+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ti+3.33+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one Ti+3.33+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Ti+3.33+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.33+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti+3.33+ atoms. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti+3.33+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Ti+3.33+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Ti+3.33+, and one P5+ atom.
