The crystal structure described by U2Fe3Ge crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded in a 13-coordinate geometry to one U(1), nine equivalent Fe(1), and three equivalent Ge(1) atoms. Fe(1) is bonded to six equivalent U(1), four equivalent Fe(1), and two equivalent Ge(1) atoms to form distorted FeU6Fe4Ge2 cuboctahedra that share corners with four equivalent Ge(1)U6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)U6Fe4Ge2 cuboctahedra, edges with six equivalent Fe(1)U6Fe4Ge2 cuboctahedra, faces with six equivalent Ge(1)U6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)U6Fe4Ge2 cuboctahedra. Ge(1) is bonded to six equivalent U(1) and six equivalent Fe(1) atoms to form GeU6Fe6 cuboctahedra that share corners with twelve equivalent Fe(1)U6Fe4Ge2 cuboctahedra, edges with six equivalent Ge(1)U6Fe6 cuboctahedra, faces with two equivalent Ge(1)U6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)U6Fe4Ge2 cuboctahedra. is represented by the CIF card [CIF]
