Ba5(FeN2)2 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted square co-planar geometry to four equivalent N(1) atoms. In the second Ba site, Ba(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. Fe(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 6-coordinate geometry to one Ba(1), four equivalent Ba(2), and one Fe(1) atom.
Ba5(FeN2)2 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted square co-planar geometry to four equivalent N(1) atoms. All Ba(1)-N(1) bond lengths are 3.03 Å. In the second Ba site, Ba(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. There are a spread of Ba(2)-N(1) bond distances ranging from 2.78-2.99 Å. Fe(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Fe(1)-N(1) bond lengths are 1.73 Å. N(1) is bonded in a 6-coordinate geometry to one Ba(1), four equivalent Ba(2), and one Fe(1) atom.
