YAg is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y is bonded in a body-centered cubic geometry to eight equivalent Ag atoms. All Y–Ag bond lengths are 3.16 Å. Ag is bonded in a body-centered cubic geometry to eight equivalent Y atoms.
Ag2Y crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Y is bonded in a distorted q6 geometry to ten equivalent Ag atoms. There are two shorter (3.06 Å) and eight longer (3.09 Å) Y–Ag bond lengths. Ag is bonded in a 10-coordinate geometry to five equivalent Y atoms.
YAg3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Y is bonded in a distorted body-centered cubic geometry to fourteen Ag atoms. There are eight shorter (3.01 Å) and six longer (3.48 Å) Y–Ag bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag is bonded to four equivalent Y and four equivalent Ag atoms to form a mixture of distorted edge, face, and corner-sharing AgY4Ag4 tetrahedra. All Ag–Ag bond lengths are 3.01 Å. In the second Ag site, Ag is bonded in a 8-coordinate geometry to six equivalent Y and eight equivalent Ag atoms.
