Materials Data on Ca4Mn4O11 by Materials Project
Abstract
Ca4Mn4O11 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.71 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.80 Å. In the third Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.74 Å. In the fourth Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.57 Å. There are four inequivalent Mn+3.50+ sites. In the first Mn+3.50+ site, Mn+3.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent MnO6 octahedra and corners with four equivalent MnO5 square pyramids. The corner-sharing octahedra tilt angles range from 22–29°. There are a spread of Mn–O bond distances ranging from 1.90–1.98 Å. In the second Mn+3.50+ site, Mn+3.50+ is bonded to five O2- atomsmore »
