EuZn1 is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Eu is bonded in a body-centered cubic geometry to eight equivalent Zn atoms. All Eu–Zn bond lengths are 3.26 Å. Zn is bonded in a body-centered cubic geometry to eight equivalent Eu atoms.
EuZn5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Eu is bonded in a 6-coordinate geometry to eighteen Zn atoms. There are six shorter (3.15 Å) and twelve longer (3.46 Å) Eu–Zn bond lengths. There are two inequivalent Zn sites.
