The crystal structure described by MgAg5Zn4 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. Mg(1) is bonded in a body-centered cubic geometry to eight equivalent Ag(1) atoms. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Zn(1) atoms. In the second Ag site, Ag(2) is bonded in a body-centered cubic geometry to four equivalent Zn(1) and four equivalent Zn(2) atoms. In the third Ag site, Ag(3) is bonded in a body-centered cubic geometry to eight equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a body-centered cubic geometry to four equivalent Ag(1) and four equivalent Ag(2) atoms. In the second Zn site, Zn(2) is bonded in a body-centered cubic geometry to four equivalent Ag(2) and four equivalent Ag(3) atoms. is represented by the CIF card [CIF]
