Materials Data on K2MnPCO7 by Materials Project
Abstract
K2MnCPO7 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 2.64–2.94 Å. Mn3+ 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 1.94–2.38 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.24 Å) and two longer (1.32 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 32–37°. There are a spread of P–O bond distances ranging from 1.54–1.59 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two equivalent K1+, one Mn3+, and one C4+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+, one Mn3+,more »
