The structure described by AgAgMg is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded in a 12-coordinate geometry to three equivalent Ag(1) and nine equivalent Ag(2) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to six equivalent Mg(1) and six equivalent Ag(2) atoms to form a mixture of face, corner, and edge-sharing AgMg6Ag6 cuboctahedra. In the second Ag site, Ag(2) is bonded to six equivalent Mg(1), two equivalent Ag(1), and four equivalent Ag(2) atoms to form a mixture of face, corner, and edge-sharing AgMg6Ag6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
