Materials Data on La3Mn4AgO12 by Materials Project
La3Mn4AgO12 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2 space group. The structure is three-dimensional. there are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.78 Å. In the second La3+ site, La3+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.46–2.78 Å. In the third La3+ site, La3+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.45–2.79 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 14–22°. There are a spread of Mn–O bond distances ranging from 1.95–2.01 Å. In the second 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 14–22°. There are a spread of Mn–O bond distances ranging from 1.95–2.01 Å. Ag1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ag–O bond distances ranging from 2.44–3.13 Å. There are eight inequivalent O2- sites.
