EuZnGe crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to six equivalent Zn(1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing EuZn6Ge6 cuboctahedra. In the second Eu site, Eu(2) is bonded to six equivalent Zn(1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing EuZn6Ge6 cuboctahedra. Zn(1) is bonded in a distorted trigonal planar geometry to three equivalent Eu(1), three equivalent Eu(2), and three equivalent Ge(1) atoms. Ge(1) is bonded in a distorted trigonal planar geometry to three equivalent Eu(1), three equivalent Eu(2), and three equivalent Zn(1) atoms.
