The compound described by MgHoAg crystallizes in the hexagonal P-62m space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Ag(2) atoms. Ho(1) is bonded in a 5-coordinate geometry to one Ag(2) and four equivalent Ag(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Ho(1) atoms. In the second Ag site, Ag(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Ho(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
