Title: Materials Data on CaLa4Ti3RuO15 by Materials Project

Abstract

CaLa4Ti3RuO15 crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Ca2+ is bonded to twelve O2- atoms to form CaO12 cuboctahedra that share corners with six equivalent CaO12 cuboctahedra, corners with six LaO12 cuboctahedra, faces with six LaO12 cuboctahedra, faces with three equivalent RuO6 octahedra, and faces with five TiO6 octahedra.

In the first La3+ site, La3+ is bonded to twelve O2- atoms to form distorted LaO12 cuboctahedra that share corners with three equivalent CaO12 cuboctahedra, corners with six equivalent LaO12 cuboctahedra, corners with three equivalent TiO6 octahedra, faces with seven LaO12 cuboctahedra, and faces with four TiO6 octahedra.
