Materials Data on Na2LiMnPCO7 by Materials Project
Abstract
Na2LiMnCPO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.27–2.87 Å. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.06–2.10 Å. Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.10–2.39 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.31 Å) C–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 45–55°. There is one shorter (1.55 Å) and three longer (1.56 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal pyramidal geometry to two equivalent Na1+, one Li1+, and one C4+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to twomore »
