The material structure described by Eu2ZnGe3 crystallizes in the hexagonal P6_3/mmc space group. Eu(1) is bonded in a 9-coordinate geometry to three equivalent Zn(1), three equivalent Ge(1), and three equivalent Ge(2) atoms. Zn(1) is bonded in a distorted trigonal planar geometry to six equivalent Eu(1) and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 6-coordinate geometry to three equivalent Eu(1) and three equivalent Ge(2) atoms. In the second Ge site, Ge(1) is bonded in a distorted trigonal planar geometry to six equivalent Eu(1) and three equivalent Zn(1) atoms. is represented by the CIF file [CIF]
