KLa4Fe crystallizes in the trigonal R3m space group. K(1) is bonded in a 10-coordinate geometry to three equivalent La(1), three equivalent La(2), and four equivalent Fe(1) atoms. All K(1)-La(1) bond lengths are 3.54 Å. All K(1)-La(2) bond lengths are 4.04 Å. There is one shorter (3.35 Å) and three longer (4.14 Å) K(1)-Fe(1) bond lengths. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to one K(1), one La(2), two equivalent La(1), and two equivalent Fe(1) atoms. The La(1)-La(2) bond length is 1.92 Å. Both La(1)-La(1) bond lengths are 1.11 Å. There is one shorter (3.43 Å) and one longer (3.71 Å) La(1)-Fe(1) bond length. In the second La site, La(2) is bonded in a 9-coordinate geometry to three equivalent K(1), three equivalent La(1), and three equivalent Fe(1) atoms. All La(2)-Fe(1) bond lengths are 3.70 Å. Fe(1) is bonded in a 13-coordinate geometry to four equivalent K(1), three equivalent La(2), and six equivalent La(1) atoms.
