CrAg3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Cr(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form CrAg12 cuboctahedra that share corners with four equivalent Cr(1)Ag12 cuboctahedra, corners with eight equivalent Ag(2)Cr4Ag8 cuboctahedra, edges with eight equivalent Cr(1)Ag12 cuboctahedra, edges with sixteen equivalent Ag(1)Cr4Ag8 cuboctahedra, faces with four equivalent Cr(1)Ag12 cuboctahedra, faces with six equivalent Ag(2)Cr4Ag8 cuboctahedra, and faces with eight equivalent Ag(1)Cr4Ag8 cuboctahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Cr(1), four equivalent Ag(1), and four equivalent Ag(2) atoms to form AgCr4Ag8 cuboctahedra that share corners with twelve equivalent Ag(1)Cr4Ag8 cuboctahedra, edges with eight equivalent Cr(1)Ag12 cuboctahedra, edges with eight equivalent Ag(1)Cr4Ag8 cuboctahedra, edges with eight equivalent Ag(2)Cr4Ag8 cuboctahedra, faces with four equivalent Cr(1)Ag12 cuboctahedra, faces with four equivalent Ag(2)Cr4Ag8 cuboctahedra, and faces with ten equivalent Ag(1)Cr4Ag8 cuboctahedra. In the second Ag site, Ag(2) is bonded to four equivalent Cr(1) and eight equivalent Ag(1) atoms to form AgCr4Ag8 cuboctahedra that share corners with four equivalent Ag(2)Cr4Ag8 cuboctahedra, corners with eight equivalent Cr(1)Ag12 cuboctahedra, edges with eight equivalent Ag(2)Cr4Ag8 cuboctahedra, edges with sixteen equivalent Ag(1)Cr4Ag8 cuboctahedra, faces with four equivalent Ag(2)Cr4Ag8 cuboctahedra, faces with six equivalent Cr(1)Ag12 cuboctahedra, and faces with eight equivalent Ag(1)Cr4Ag8 cuboctahedra.
