The compound described by EuAg2Al3 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 Al(1) atoms. Ag(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1) and six equivalent Al(1) atoms. Al(1) is bonded to four equivalent Eu(1) and four equivalent Ag(1) atoms to form a mixture of distorted corner, face, and edge-sharing AlEu4Ag4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
