The compound described by EuAg3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Eu(1) is bonded in a distorted body-centered cubic geometry to six equivalent Ag(2) and eight equivalent Ag(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Eu(1) and four equivalent Ag(2) atoms to form a mixture of distorted edge, corner, and face-sharing AgEu4Ag4 tetrahedra. In the second Ag site, Ag(2) is bonded in a 14-coordinate geometry to six equivalent Eu(1) and eight equivalent Ag(1) atoms. is represented by the CIF file [CIF]
