The compound described by EuTl3 is beta Cu3Ti-like structured and crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded to four equivalent Tl(2) and eight equivalent Tl(1) atoms to form a mixture of face and corner-sharing EuTl12 cuboctahedra. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) atoms. In the second Tl site, Tl(2) is bonded in a 4-coordinate geometry to four equivalent Eu(1) atoms. is represented by the CIF card [CIF]
