Title: Materials Data on CaLaMn2O6 by Materials Project

Abstract

CaLaMn2O6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 9-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.38–2.70 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 2.38–2.71 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.43–2.73 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.43–2.72 Å. There are two inequivalent Mn+3.50+ sites. In the first Mn+3.50+ site, Mn+3.50+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 21–25°. There are a spread of Mn–O bond distances ranging from 1.97–1.99 Å. In the second Mn+3.50+ site, Mn+3.50+ is bonded to six O2- atoms to form corner-sharing MnO6more » octahedra. The corner-sharing octahedra tilt angles range from 21–25°. There are a spread of Mn–O bond distances ranging from 1.97–2.01 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to one Ca2+, two La3+, and two Mn+3.50+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Ca2+, one La3+, and two equivalent Mn+3.50+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Ca2+, one La3+, and two equivalent Mn+3.50+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Ca2+, one La3+, and two equivalent Mn+3.50+ atoms. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to one Ca2+, two La3+, and two Mn+3.50+ atoms. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ca2+, one La3+, and two equivalent Mn+3.50+ atoms. In the seventh O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ca2+, one La3+, and two equivalent Mn+3.50+ atoms. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to one Ca2+, one La3+, and two equivalent Mn+3.50+ atoms.« less
