The structure described by YbAgSn crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 12-coordinate geometry to six equivalent Ag(1) and six equivalent Sn(1) atoms. In the second Yb site, Yb(2) is bonded to three equivalent Ag(1), three equivalent Ag(2), three equivalent Sn(1), and three equivalent Sn(2) atoms to form a mixture of distorted face and edge-sharing YbAg6Sn6 cuboctahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to three equivalent Yb(1), three equivalent Yb(2), one Sn(2), and three equivalent Sn(1) atoms. In the second Ag site, Ag(2) is bonded in a 9-coordinate geometry to six equivalent Yb(2) and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to three equivalent Yb(1), three equivalent Yb(2), three equivalent Ag(1), and one Sn(1) atom. In the second Sn site, Sn(2) is bonded in a 11-coordinate geometry to six equivalent Yb(2), two equivalent Ag(1), and three equivalent Ag(2) atoms. is represented by the CIF card [CIF]
