Zn3Ge is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Zn sites. In the first Zn site, Zn is bonded to eight Zn and four equivalent Ge atoms to form ZnZn8Ge4 cuboctahedra that share corners with twelve equivalent ZnZn8Ge4 cuboctahedra, edges with eight equivalent GeZn12 cuboctahedra, edges with sixteen ZnZn8Ge4 cuboctahedra, faces with four equivalent GeZn12 cuboctahedra, and faces with fourteen ZnZn8Ge4 cuboctahedra. There are four shorter (2.82 Å) and four longer (2.86 Å) Zn–Zn bond lengths. All Zn–Ge bond lengths are 2.86 Å. In the second Zn site, Zn is bonded to eight equivalent Zn and four equivalent Ge atoms to form distorted ZnZn8Ge4 cuboctahedra that share corners with four equivalent ZnZn8Ge4 cuboctahedra, corners with eight equivalent GeZn12 cuboctahedra, edges with twenty-four ZnZn8Ge4 cuboctahedra, faces with six equivalent GeZn12 cuboctahedra, and faces with twelve ZnZn8Ge4 cuboctahedra. All Zn–Ge bond lengths are 2.82 Å. Ge is bonded to twelve Zn atoms to form GeZn12 cuboctahedra that share corners with four equivalent GeZn12 cuboctahedra, corners with eight equivalent ZnZn8Ge4 cuboctahedra, edges with eight equivalent GeZn12 cuboctahedra, edges with sixteen equivalent ZnZn8Ge4 cuboctahedra, faces with four equivalent GeZn12 cuboctahedra, and faces with fourteen ZnZn8Ge4 cuboctahedra.
