Title: Materials Data on Ca5Cr3O13 by Materials Project

Abstract

Ca5Cr3O13 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are four inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–3.05 Å. In the second Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.19–2.61 Å. In the third Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.16–2.75 Å. In the fourth Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 pentagonal pyramids that share corners with three equivalent CrO4 tetrahedra and an edgeedge with one CrO4 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.21–2.55 Å. There are three inequivalent Cr+5.33+ sites. In the first Cr+5.33+ site, Cr+5.33+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.66 Å) and one longer (1.68 Å) Cr–O bond length. In the second Cr+5.33+ site, Cr+5.33+ is bonded to four O2- atoms to form CrO4 tetrahedra thatmore » share corners with three equivalent CaO6 pentagonal pyramids. There is one shorter (1.72 Å) and three longer (1.73 Å) Cr–O bond length. In the third Cr+5.33+ site, Cr+5.33+ is bonded to four O2- atoms to form CrO4 tetrahedra that share an edgeedge with one CaO6 pentagonal pyramid. There are a spread of Cr–O bond distances ranging from 1.71–1.74 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three Ca2+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ca2+ and one Cr+5.33+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one Cr+5.33+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one Cr+5.33+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Ca2+ and one Cr+5.33+ atom. In the sixth O2- site, O2- is bonded in a distorted tetrahedral geometry to three Ca2+ and one Cr+5.33+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one Cr+5.33+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one Cr+5.33+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one Cr+5.33+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one Cr+5.33+ atom.« less
