The compound described by Eu2ZnBi2 crystallizes in the hexagonal P-6m2 space group. Eu(1) is bonded in a 9-coordinate geometry to three equivalent Zn(1), three equivalent Bi(1), and three equivalent Bi(2) atoms. Zn(1) is bonded in a distorted trigonal planar geometry to six equivalent Eu(1) and three equivalent Bi(2) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to six equivalent Eu(1) atoms. In the second Bi site, Bi(2) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent Zn(1) atoms. is represented by the CIF file [CIF]
