Eu3Ag2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. In the second Eu site, Eu(2) is bonded in a square co-planar geometry to four equivalent Ag(1) atoms. Ag(1) is bonded in a 9-coordinate geometry to two equivalent Eu(2), six equivalent Eu(1), and one Ag(1) atom.
Eu3Ag2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. There are four shorter (3.29 Å) and two longer (3.33 Å) Eu(1)-Ag(1) bond lengths. In the second Eu site, Eu(2) is bonded in a square co-planar geometry to four equivalent Ag(1) atoms. All Eu(2)-Ag(1) bond lengths are 3.35 Å. Ag(1) is bonded in a 9-coordinate geometry to two equivalent Eu(2), six equivalent Eu(1), and one Ag(1) atom. The Ag(1)-Ag(1) bond length is 2.93 Å.
