The compound described by Fe5(GeN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 3-coordinate geometry to one N(1), one N(2), and one N(3) atom. In the second Fe site, Fe(2) is bonded in a distorted see-saw-like geometry to one N(2), one N(3), and two equivalent N(1) atoms. In the third Fe site, Fe(3) is bonded in a distorted tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Ge(1) is bonded in a distorted L-shaped geometry to two equivalent N(3) atoms. There are three inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to one Fe(1), one Fe(2), and one Fe(3) atom. In the second N site, N(3) is bonded to one Fe(1), one Fe(2), and two equivalent Ge(1) atoms to form distorted NFe2Ge2 tetrahedra that share corners with three equivalent N(1)Fe4 trigonal pyramids and  an edgeedge with one N(3)Fe2Ge2 tetrahedra. In the third N site, N(1) is bonded to one Fe(1), one Fe(3), and two equivalent Fe(2) atoms to form NFe4 trigonal pyramids that share corners with three equivalent N(3)Fe2Ge2 tetrahedra and  a faceface with one N(1)Fe4 trigonal pyramid. is represented by the Crystallographic Information File (CIF) [CIF]
