The material structure described by Fe3Ge2 crystallizes in the trigonal P-3m1 space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted body-centered cubic geometry to three equivalent Fe(2) and five equivalent Ge(1) atoms. In the second Fe site, Fe(2) is bonded to six equivalent Fe(1) and six equivalent Ge(1) atoms to form face-sharing FeFe6Ge6 cuboctahedra. Ge(1) is bonded in a 5-coordinate geometry to three equivalent Fe(2) and five equivalent Fe(1) atoms. is represented by the CIF card [CIF]
