Y2Fe3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. In the second Fe site, Fe(2) is bonded in a distorted tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to three equivalent Y(1), one Fe(2), and two equivalent Fe(1) atoms. In the second N site, N(2) is bonded in a 5-coordinate geometry to three equivalent Y(1), one Fe(1), and one Fe(2) atom.
Y2Fe3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. There are a spread of Y(1)-N(1) bond distances ranging from 2.42-2.68 Å. There are a spread of Y(1)-N(2) bond distances ranging from 2.33-2.59 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. The Fe(1)-N(2) bond length is 1.81 Å. There is one shorter (1.86 Å) and one longer (1.87 Å) Fe(1)-N(1) bond length.
