CaLaFe3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Ca(1) is bonded to six equivalent Fe(1) atoms to form CaFe6 octahedra that share corners with six equivalent Ca(1)Fe6 octahedra and faces with eight equivalent La(1)Fe12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.12 Å) and three longer (2.75 Å) Ca(1)-Fe(1) bond lengths. La(1) is bonded to twelve equivalent Fe(1) atoms to form distorted LaFe12 cuboctahedra that share corners with twelve equivalent La(1)Fe12 cuboctahedra, faces with six equivalent La(1)Fe12 cuboctahedra, and faces with eight equivalent Ca(1)Fe6 octahedra. There are a spread of La(1)-Fe(1) bond distances ranging from 2.99-3.89 Å. Fe(1) is bonded in a 1-coordinate geometry to two equivalent Ca(1) and four equivalent La(1) atoms.
