CaLaFe2 crystallizes in the trigonal R3m space group. Ca(1) is bonded in a 11-coordinate geometry to four equivalent La(1), four equivalent Fe(2), and six equivalent Fe(1) atoms. There is one shorter (2.29 Å) and three longer (3.30 Å) Ca(1)-La(1) bond lengths. There are three shorter (2.93 Å) and one longer (3.23 Å) Ca(1)-Fe(2) bond length. There are three shorter (3.21 Å) and three longer (3.75 Å) Ca(1)-Fe(1) bond lengths. La(1) is bonded in a 11-coordinate geometry to four equivalent Ca(1), three equivalent Fe(2), and four equivalent Fe(1) atoms. All La(1)-Fe(2) bond lengths are 3.21 Å. There are three shorter (2.93 Å) and one longer (3.23 Å) La(1)-Fe(1) bond length. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 14-coordinate geometry to six equivalent Ca(1), four equivalent La(1), and four equivalent Fe(2) atoms. There are three shorter (2.93 Å) and one longer (3.23 Å) Fe(1)-Fe(2) bond length. In the second Fe site, Fe(2) is bonded in a 4-coordinate geometry to four equivalent Ca(1), three equivalent La(1), and four equivalent Fe(1) atoms.
