Title: Materials Data on SrNd2Mn3O9 by Materials Project

Abstract

SrNd2Mn3O9 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Sr–O bond distances ranging from 2.49–3.12 Å. There are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.39–2.71 Å. In the second Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.41–2.80 Å. There are two inequivalent Mn+3.33+ sites. In the first Mn+3.33+ site, Mn+3.33+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 17–26°. There are a spread of Mn–O bond distances ranging from 1.96–2.03 Å. In the second Mn+3.33+ site, Mn+3.33+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 23–27°. There are four shorter (1.99 Å) and two longer (2.01 Å) Mn–O bond lengths. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in amore » 5-coordinate geometry to one Sr2+, two equivalent Nd3+, and two Mn+3.33+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to one Sr2+, two Nd3+, and two Mn+3.33+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+, two equivalent Nd3+, and two equivalent Mn+3.33+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, one Nd3+, and two equivalent Mn+3.33+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, two Nd3+, and two equivalent Mn+3.33+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Nd3+, and two equivalent Mn+3.33+ atoms.« less
