The structure described by V3Ag is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to four equivalent V(1), four equivalent V(2), and four equivalent Ag(1) atoms to form VV8Ag4 cuboctahedra that share corners with twelve equivalent V(1)V8Ag4 cuboctahedra, edges with eight equivalent V(1)V8Ag4 cuboctahedra, edges with eight equivalent V(2)V8Ag4 cuboctahedra, edges with eight equivalent Ag(1)V12 cuboctahedra, faces with four equivalent V(2)V8Ag4 cuboctahedra, faces with four equivalent Ag(1)V12 cuboctahedra, and faces with ten equivalent V(1)V8Ag4 cuboctahedra. In the second V site, V(2) is bonded to eight equivalent V(1) and four equivalent Ag(1) atoms to form distorted VV8Ag4 cuboctahedra that share corners with four equivalent V(2)V8Ag4 cuboctahedra, corners with eight equivalent Ag(1)V12 cuboctahedra, edges with eight equivalent V(2)V8Ag4 cuboctahedra, edges with sixteen equivalent V(1)V8Ag4 cuboctahedra, faces with four equivalent V(2)V8Ag4 cuboctahedra, faces with six equivalent Ag(1)V12 cuboctahedra, and faces with eight equivalent V(1)V8Ag4 cuboctahedra. Ag(1) is bonded to four equivalent V(2) and eight equivalent V(1) atoms to form AgV12 cuboctahedra that share corners with four equivalent Ag(1)V12 cuboctahedra, corners with eight equivalent V(2)V8Ag4 cuboctahedra, edges with eight equivalent Ag(1)V12 cuboctahedra, edges with sixteen equivalent V(1)V8Ag4 cuboctahedra, faces with four equivalent Ag(1)V12 cuboctahedra, faces with six equivalent V(2)V8Ag4 cuboctahedra, and faces with eight equivalent V(1)V8Ag4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
