CeY4Zn5 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded in a body-centered cubic geometry to eight equivalent Zn(1) atoms. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a body-centered cubic geometry to four equivalent Zn(1) and four equivalent Zn(2) atoms. In the second Y site, Y(2) is bonded in a body-centered cubic geometry to four equivalent Zn(2) and four equivalent Zn(3) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a body-centered cubic geometry to four equivalent Ce(1) and four equivalent Y(1) atoms. In the second Zn site, Zn(2) is bonded in a body-centered cubic geometry to four equivalent Y(1) and four equivalent Y(2) atoms. In the third Zn site, Zn(3) is bonded in a body-centered cubic geometry to eight equivalent Y(2) atoms.
