The material structure described by Ca2MgAg3 crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded in a 16-coordinate geometry to four equivalent Ca(1), three equivalent Mg(1), and nine equivalent Ag(1) atoms. Mg(1) is bonded to six equivalent Ca(1) and six equivalent Ag(1) atoms to form a mixture of distorted edge and face-sharing MgCa6Ag6 cuboctahedra. Ag(1) is bonded in a 12-coordinate geometry to six equivalent Ca(1), two equivalent Mg(1), and four equivalent Ag(1) atoms. is represented by the CIF file [CIF]
