Materials Data on La5MnRe3O16 by Materials Project
La5Re3MnO16 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.42–2.66 Å. In the second La3+ site, La3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of La–O bond distances ranging from 2.42–2.56 Å. In the third La3+ site, La3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.42–2.62 Å. There are two inequivalent Re5+ sites. In the first Re5+ site, Re5+ is bonded to six O2- atoms to form ReO6 octahedra that share a cornercorner with one MnO6 octahedra and an edgeedge with one ReO6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are a spread of Re–O bond distances ranging from 1.95–2.07 Å. In the second Re5+ site, Re5+ is bonded to six O2- atoms to form ReO6 octahedra that share corners with four equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 27–33°. There are a spread of Re–O bond distances ranging from 1.92–2.02 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six ReO6 octahedra. The corner-sharing octahedra tilt angles range from 27–33°. There are a spread of Mn–O bond distances ranging from 2.14–2.21 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one La3+ and two equivalent Re5+ atoms. In the second O2- site, O2- is bonded to three La3+ and one Re5+ atom to form corner-sharing OLa3Re tetrahedra. In the third O2- site, O2- is bonded to two La3+, one Re5+, and one Mn2+ atom to form distorted corner-sharing OLa2MnRe tetrahedra. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two La3+ and one Re5+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to three La3+ and one Re5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to three La3+ and one Re5+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent La3+, one Re5+, and one Mn2+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one La3+, one Re5+, and one Mn2+ atom.
