Materials Data on Ca3Mn2(IrO6)2 by Materials Project
Abstract
Ca3Mn2(IrO6)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first 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 2.34–2.56 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 2.31–2.72 Å. In the third 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 2.32–2.67 Å. There are two inequivalent Mn+4.50+ sites. In the first Mn+4.50+ site, Mn+4.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six IrO6 octahedra. The corner-sharing octahedra tilt angles range from 27–33°. There are a spread of Mn–O bond distances ranging from 1.97–2.08 Å. In the second Mn+4.50+ site, Mn+4.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six IrO6 octahedra. The corner-sharing octahedra tilt angles range from 27–33°. There are a spread of Mn–O bond distances ranging from 1.98–2.08 Å. There are two inequivalent Ir+4.50+ sites.more »
