The material described by Mg4Ag5Cd is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a body-centered cubic geometry to four equivalent Ag(1) and four equivalent Ag(2) atoms. In the second Mg site, Mg(2) is bonded in a body-centered cubic geometry to four equivalent Ag(2) and four equivalent Ag(3) 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 Cd(1) atoms. In the second Ag site, Ag(2) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Mg(2) atoms. In the third Ag site, Ag(3) is bonded in a body-centered cubic geometry to eight equivalent Mg(2) atoms. Cd(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
