The crystal structure described by Ag3Dy is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form DyAg12 cuboctahedra that share corners with four equivalent Dy(1)Ag12 cuboctahedra, corners with eight equivalent Ag(2)Dy4Ag8 cuboctahedra, corners with sixteen equivalent Ag(1)Dy4Ag4 cuboctahedra, edges with eight equivalent Dy(1)Ag12 cuboctahedra, edges with eight equivalent Ag(1)Dy4Ag4 cuboctahedra, faces with four equivalent Dy(1)Ag12 cuboctahedra, and faces with six equivalent Ag(2)Dy4Ag8 cuboctahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Dy(1) and four equivalent Ag(2) atoms to form distorted AgDy4Ag4 cuboctahedra that share corners with eight equivalent Dy(1)Ag12 cuboctahedra, corners with eight equivalent Ag(1)Dy4Ag4 cuboctahedra, corners with eight equivalent Ag(2)Dy4Ag8 cuboctahedra, edges with four equivalent Dy(1)Ag12 cuboctahedra, edges with four equivalent Ag(2)Dy4Ag8 cuboctahedra, edges with twelve equivalent Ag(1)Dy4Ag4 cuboctahedra, and faces with six equivalent Ag(1)Dy4Ag4 cuboctahedra. In the second Ag site, Ag(2) is bonded to four equivalent Dy(1) and eight equivalent Ag(1) atoms to form AgDy4Ag8 cuboctahedra that share corners with four equivalent Ag(2)Dy4Ag8 cuboctahedra, corners with eight equivalent Dy(1)Ag12 cuboctahedra, corners with sixteen equivalent Ag(1)Dy4Ag4 cuboctahedra, edges with eight equivalent Ag(1)Dy4Ag4 cuboctahedra, edges with eight equivalent Ag(2)Dy4Ag8 cuboctahedra, faces with four equivalent Ag(2)Dy4Ag8 cuboctahedra, and faces with six equivalent Dy(1)Ag12 cuboctahedra. is represented by the CIF card [CIF]
