Materials Data on Li3BePCO7 by Materials Project
Li3BeCPO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.52 Å. In the second Li1+ site, Li1+ is bonded in a 3-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.86–2.49 Å. In the third 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 1.94–2.52 Å. Be2+ is bonded to four O2- atoms to form BeO4 tetrahedra that share corners with two equivalent PO4 tetrahedra. There are a spread of Be–O bond distances ranging from 1.61–1.74 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.32 Å) C–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent BeO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Be2+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Li1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one Be2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Be2+, and one C4+ atom. In the sixth O2- site, O2- is bonded to three Li1+ and one P5+ atom to form distorted corner-sharing OLi3P tetrahedra. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Be2+, and one P5+ atom.
