Fe3Ge is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to eight equivalent Fe(1) and four equivalent Ge(1) atoms to form FeFe8Ge4 cuboctahedra that share corners with twelve equivalent Fe(1)Fe8Ge4 cuboctahedra, edges with eight equivalent Ge(1)Fe12 cuboctahedra, edges with sixteen equivalent Fe(1)Fe8Ge4 cuboctahedra, faces with four equivalent Ge(1)Fe12 cuboctahedra, and faces with fourteen equivalent Fe(1)Fe8Ge4 cuboctahedra. Ge(1) is bonded to twelve equivalent Fe(1) atoms to form GeFe12 cuboctahedra that share corners with twelve equivalent Ge(1)Fe12 cuboctahedra, edges with twenty-four equivalent Fe(1)Fe8Ge4 cuboctahedra, faces with six equivalent Ge(1)Fe12 cuboctahedra, and faces with twelve equivalent Fe(1)Fe8Ge4 cuboctahedra.
