The crystal structure described by Mg5Ag crystallizes in the monoclinic Cm space group. There are five inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 2-coordinate geometry to two equivalent Mg(3), two equivalent Mg(5), three equivalent Mg(2), and two equivalent Ag(1) atoms. In the second Mg site, Mg(2) is bonded to one Mg(5), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), three equivalent Mg(1), and two equivalent Ag(1) atoms to form distorted MgMg10Ag2 cuboctahedra that share corners with six equivalent Mg(2)Mg10Ag2 cuboctahedra, edges with six equivalent Mg(3)Mg11Ag cuboctahedra, faces with two equivalent Mg(2)Mg10Ag2 cuboctahedra, and faces with three equivalent Mg(3)Mg11Ag cuboctahedra. In the third Mg site, Mg(3) is bonded to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(5), three equivalent Mg(4), and one Ag(1) atom to form distorted MgMg11Ag cuboctahedra that share corners with six equivalent Mg(3)Mg11Ag cuboctahedra, edges with six equivalent Mg(2)Mg10Ag2 cuboctahedra, faces with two equivalent Mg(3)Mg11Ag cuboctahedra, and faces with three equivalent Mg(2)Mg10Ag2 cuboctahedra. In the fourth Mg site, Mg(4) is bonded in a 2-coordinate geometry to two equivalent Mg(2), two equivalent Mg(5), three equivalent Mg(3), and two equivalent Ag(1) atoms. In the fifth Mg site, Mg(5) is bonded in a 12-coordinate geometry to one Mg(2), two equivalent Mg(1), two equivalent Mg(3), two equivalent Mg(4), two equivalent Mg(5), and three equivalent Ag(1) atoms. Ag(1) is bonded in a 10-coordinate geometry to one Mg(3), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(4), and three equivalent Mg(5) atoms. is represented by the CIF card [CIF]
