EuI2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded to three equivalent I(2) and four equivalent I(1) atoms to form a mixture of distorted corner and edge-sharing EuI7 pentagonal bipyramids. There are two inequivalent I sites. In the first I site, I(2) is bonded in a trigonal non-coplanar geometry to three equivalent Eu(1) atoms. In the second I site, I(1) is bonded to four equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing IEu4 trigonal pyramids.

Eu(1) is bonded to three equivalent I(2) and four equivalent I(1) atoms to form a mixture of distorted corner and edge-sharing EuI7 pentagonal bipyramids. There are two shorter (3.29 Å) and one longer (3.30 Å) Eu(1)-I(2) bond length. There are a spread of Eu(1)-I(1) bond distances ranging from 3.35-3.45 Å. There are two inequivalent I sites. In the first I site, I(2) is bonded in a trigonal non-coplanar geometry to three equivalent Eu(1) atoms. In the second I site, I(1) is bonded to four equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing IEu4 trigonal pyramids.
