CaAg3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Ca(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form CaAg12 cuboctahedra that share corners with four equivalent Ca(1)Ag12 cuboctahedra, corners with eight equivalent Ag(2)Ca4Ag8 cuboctahedra, edges with eight equivalent Ca(1)Ag12 cuboctahedra, faces with four equivalent Ca(1)Ag12 cuboctahedra, and faces with six equivalent Ag(2)Ca4Ag8 cuboctahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to four equivalent Ca(1) and four equivalent Ag(2) atoms. In the second Ag site, Ag(2) is bonded to four equivalent Ca(1) and eight equivalent Ag(1) atoms to form distorted AgCa4Ag8 cuboctahedra that share corners with four equivalent Ag(2)Ca4Ag8 cuboctahedra, corners with eight equivalent Ca(1)Ag12 cuboctahedra, edges with eight equivalent Ag(2)Ca4Ag8 cuboctahedra, faces with four equivalent Ag(2)Ca4Ag8 cuboctahedra, and faces with six equivalent Ca(1)Ag12 cuboctahedra.
