NaYAg2 crystallizes in the trigonal R3m space group. Na(1) is bonded in a 10-coordinate geometry to three equivalent Y(1), three equivalent Ag(1), and four equivalent Ag(2) atoms. All Na(1)-Y(1) bond lengths are 2.90 Å. All Na(1)-Ag(1) bond lengths are 3.27 Å. There is one shorter (2.81 Å) and three longer (3.16 Å) Na(1)-Ag(2) bond lengths. Y(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), three equivalent Ag(2), and four equivalent Ag(1) atoms. All Y(1)-Ag(2) bond lengths are 3.27 Å. There is one shorter (2.81 Å) and three longer (3.16 Å) Y(1)-Ag(1) bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 1-coordinate geometry to three equivalent Na(1) and four equivalent Y(1) atoms. In the second Ag site, Ag(2) is bonded in a 1-coordinate geometry to four equivalent Na(1) and three equivalent Y(1) atoms.
