Fe5CdN4 crystallizes in the orthorhombic Pmmn space group. 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(1) and two equivalent N(2) atoms. In the second Fe site, Fe(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. Cd(1) is bonded in a 2-coordinate geometry to two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one Fe(2), two equivalent Fe(1), and one Cd(1) atom. In the second N site, N(2) is bonded to one Fe(2) and four equivalent Fe(1) atoms to form a mixture of distorted corner and edge-sharing NFe5 trigonal bipyramids.

In the first Fe site, Fe(1) is bonded in a distorted trigonal non-coplanar geometry to one N(1) and two equivalent N(2) atoms. The Fe(1)-N(1) bond length is 1.73 Å. There is one shorter (1.91 Å) and one longer (1.93 Å) Fe(1)-N(2) bond length. In the second Fe site, Fe(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Fe(2)-N(1) bond lengths are 1.85 Å. Both Fe(2)-N(2) bond lengths are 1.98 Å. Cd(1) is bonded in a 2-coordinate geometry to two equivalent N(1) atoms. Both Cd(1)-N(1) bond lengths are 2.50 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one Fe(2), two equivalent Fe(1), and one Cd(1) atom.
