Ba3Ag2 crystallizes in the trigonal R-3 space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in an octahedral geometry to six equivalent Ag(1) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. In the third Ba site, Ba(3) is bonded in a distorted rectangular see-saw-like geometry to five equivalent Ag(1) atoms. Ag(1) is bonded in a 9-coordinate geometry to one Ba(1), two equivalent Ba(2), five equivalent Ba(3), and one Ag(1) atom.
Ba3Ag2 crystallizes in the trigonal R-3 space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in an octahedral geometry to six equivalent Ag(1) atoms. All Ba(1)-Ag(1) bond lengths are 3.58 Å. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. There are three shorter (3.44 Å) and three longer (3.53 Å) Ba(2)-Ag(1) bond lengths. In the third Ba site, Ba(3) is bonded in a distorted rectangular see-saw-like geometry to five equivalent Ag(1) atoms. There are a spread of Ba(3)-Ag(1) bond distances ranging from 3.51-4.23 Å. Ag(1) is bonded in a 9-coordinate geometry to one Ba(1), two equivalent Ba(2), five equivalent Ba(3), and one Ag(1) atom. The Ag(1)-Ag(1) bond length is 3.02 Å.
