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.
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. There is one shorter (3.46 Å) and three longer (3.63 Å) Ca(1)-Ca(1) bond lengths. All Ca(1)-Mg(1) bond lengths are 3.51 Å. There are three shorter (3.28 Å) and six longer (3.47 Å) Ca(1)-Ag(1) bond lengths. 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. All Mg(1)-Ag(1) bond lengths are 2.87 Å. Ag(1) is bonded in a 12-coordinate geometry to six equivalent Ca(1), two equivalent Mg(1), and four equivalent Ag(1) atoms.
