The material described by EuAg5 crystallizes in the hexagonal P6/mmm space group. Eu(1) is bonded in a distorted hexagonal planar geometry to six equivalent Ag(1) and twelve equivalent Ag(2) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 12-coordinate geometry to three equivalent Eu(1), three equivalent Ag(1), and six equivalent Ag(2) atoms. In the second Ag site, Ag(2) is bonded to four equivalent Eu(1), four equivalent Ag(1), and four equivalent Ag(2) atoms to form a mixture of edge, corner, and face-sharing AgEu4Ag8 cuboctahedra. is represented by the CIF card [CIF]
