Na3FeN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. Fe(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing FeN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted hexagonal bipyramidal geometry to six equivalent Na(1) and two equivalent Fe(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent Fe(1) atoms.
Na3FeN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. The Na(1)-N(1) bond length is 2.52 Å. There is one shorter (2.30 Å) and one longer (2.43 Å) Na(1)-N(2) bond length. Fe(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing FeN4 tetrahedra. The Fe(1)-N(1) bond length is 1.99 Å. All Fe(1)-N(2) bond lengths are 2.11 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted hexagonal bipyramidal geometry to six equivalent Na(1) and two equivalent Fe(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent Fe(1) atoms.
