Eu is Protactinium-like structured and crystallizes in the monoclinic C2/c space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 10-coordinate geometry to four equivalent Eu(2) and six equivalent Eu(1) atoms. In the second Eu site, Eu(2) is bonded in a 10-coordinate geometry to two equivalent Eu(2) and eight equivalent Eu(1) atoms.

In the first Eu site, Eu(1) is bonded in a 10-coordinate geometry to four equivalent Eu(2) and six equivalent Eu(1) atoms. There are a spread of Eu(1)-Eu(2) bond distances ranging from 3.73-3.97 Å. There are a spread of Eu(1)-Eu(1) bond distances ranging from 3.72-3.97 Å. In the second Eu site, Eu(2) is bonded in a 10-coordinate geometry to two equivalent Eu(2) and eight equivalent Eu(1) atoms. Both Eu(2)-Eu(2) bond lengths are 3.87 Å.
