Title: Materials Data on La4SmMn5O15 by Materials Project

Abstract

SmLa4Mn5O15 is (Cubic) Perovskite-derived structured and crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. Sm3+ is bonded to twelve O2- atoms to form SmO12 cuboctahedra that share corners with two equivalent SmO12 cuboctahedra, corners with ten LaO12 cuboctahedra, faces with two equivalent SmO12 cuboctahedra, faces with four equivalent LaO12 cuboctahedra, and faces with eight MnO6 octahedra. There are a spread of Sm–O bond distances ranging from 2.73–2.78 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with four equivalent SmO12 cuboctahedra, corners with eight LaO12 cuboctahedra, faces with two equivalent SmO12 cuboctahedra, faces with four LaO12 cuboctahedra, and faces with eight MnO6 octahedra. There are seven shorter (2.78 Å) and five longer (2.80 Å) La–O bond lengths. In the second La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share a cornercorner with one SmO12 cuboctahedra, corners with eleven LaO12 cuboctahedra, faces with six LaO12 cuboctahedra, and faces with eight MnO6 octahedra. There are a spread of La–O bond distances ranging from 2.77–2.83 Å. There are three inequivalent Mn3+ sites. In the first Mn3+ site,more » Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six MnO6 octahedra and faces with eight LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. There is one shorter (1.96 Å) and five longer (1.97 Å) Mn–O bond length. In the second Mn3+ site, Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six MnO6 octahedra, faces with two equivalent SmO12 cuboctahedra, and faces with six LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are a spread of Mn–O bond distances ranging from 1.97–1.99 Å. In the third Mn3+ site, Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six MnO6 octahedra, faces with four equivalent SmO12 cuboctahedra, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. There is four shorter (1.95 Å) and two longer (1.97 Å) Mn–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent La3+ and two equivalent Mn3+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four La3+ and two Mn3+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sm3+, two equivalent La3+, and two Mn3+ atoms. In the fourth O2- site, O2- is bonded in a distorted linear geometry to four equivalent La3+ and two equivalent Mn3+ atoms. In the fifth O2- site, O2- is bonded in a distorted linear geometry to four La3+ and two Mn3+ atoms. In the sixth O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sm3+, two equivalent La3+, and two Mn3+ atoms. In the seventh O2- site, O2- is bonded in a distorted linear geometry to four La3+ and two equivalent Mn3+ atoms. In the eighth O2- site, O2- is bonded in a distorted linear geometry to one Sm3+, three La3+, and two equivalent Mn3+ atoms. In the ninth O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sm3+, two equivalent La3+, and two equivalent Mn3+ atoms.« less
