BaBeFeCd crystallizes in the trigonal R3m space group. Ba(1) is bonded in a 10-coordinate geometry to three equivalent Be(1), four equivalent Fe(1), and three equivalent Cd(1) atoms. All Ba(1)-Be(1) bond lengths are 2.94 Å. There is one shorter (2.64 Å) and three longer (3.28 Å) Ba(1)-Fe(1) bond lengths. All Ba(1)-Cd(1) bond lengths are 3.14 Å. Be(1) is bonded to three equivalent Ba(1) and one Cd(1) atom to form distorted corner-sharing BeBa3Cd trigonal pyramids. The Be(1)-Cd(1) bond length is 2.64 Å. Fe(1) is bonded in a 1-coordinate geometry to four equivalent Ba(1) and four equivalent Cd(1) atoms. There is one shorter (2.64 Å) and three longer (3.28 Å) Fe(1)-Cd(1) bond lengths. Cd(1) is bonded in a 8-coordinate geometry to three equivalent Ba(1), one Be(1), and four equivalent Fe(1) atoms.
