Title: Materials Data on La7Mn8O24 by Materials Project

Abstract

La7Mn8O24 is Orthorhombic Perovskite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are seven inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to eight O2- atoms to form distorted LaO8 cuboctahedra that share corners with four equivalent LaO12 cuboctahedra and edges with eight MnO6 octahedra.
