Materials Data on LiMo2P2O9 by Materials Project
LiMo2P2O9 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.00–2.70 Å. There are two inequivalent Mo+3.50+ sites. In the first Mo+3.50+ site, Mo+3.50+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with two equivalent MoO6 octahedra, corners with three equivalent PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Mo–O bond distances ranging from 1.96–2.16 Å. In the second Mo+3.50+ site, Mo+3.50+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with two equivalent MoO6 octahedra, corners with four PO4 tetrahedra, and edges with two equivalent MoO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Mo–O bond distances ranging from 2.14–2.17 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 five MoO6 octahedra. The corner-sharing octahedra tilt angles range from 2–51°. There is three shorter (1.53 Å) and one longer (1.57 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 two equivalent MoO6 octahedra and an edgeedge with one MoO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mo+3.50+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mo+3.50+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mo+3.50+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one Mo+3.50+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Mo+3.50+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mo+3.50+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mo+3.50+ and one P5+ atom.
