The structure described by Yb5Ag3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to two equivalent Ag(2) and three equivalent Ag(1) atoms to form a mixture of distorted corner, face, and edge-sharing YbAg5 trigonal bipyramids. In the second Yb site, Yb(2) is bonded in a distorted square co-planar geometry to two equivalent Ag(2) and four equivalent Ag(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(2) is bonded in a 10-coordinate geometry to two equivalent Yb(2) and eight equivalent Yb(1) atoms. In the second Ag site, Ag(1) is bonded in a 9-coordinate geometry to two equivalent Yb(2), six equivalent Yb(1), and one Ag(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
