Materials Data on K2ErPCO7 by Materials Project
Abstract
K2ErCPO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.53–3.26 Å. Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Er–O bond distances ranging from 2.21–2.32 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.25–1.33 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent ErO6 octahedra. The corner-sharing octahedra tilt angles range from 37–43°. There is two shorter (1.55 Å) and two longer (1.57 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent K1+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent K1+, one Er3+, and one C4+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+, one Er3+, andmore »
