EuZn13 crystallizes in the cubic Fm-3c space group. Eu(1) is bonded in a 24-coordinate geometry to twenty-four equivalent Zn(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to two equivalent Eu(1), one Zn(2), and nine equivalent Zn(1) atoms. In the second Zn site, Zn(2) is bonded in a cuboctahedral geometry to twelve equivalent Zn(1) atoms.
