SrI2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pbca space group. Sr(1) is bonded to three equivalent I(1) and four equivalent I(2) atoms to form a mixture of distorted edge and corner-sharing SrI7 pentagonal bipyramids. There are two inequivalent I sites. In the first I site, I(1) is bonded in a trigonal planar geometry to three equivalent Sr(1) atoms. In the second I site, I(2) is bonded to four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing ISr4 tetrahedra.

Sr(1) is bonded to three equivalent I(1) and four equivalent I(2) atoms to form a mixture of distorted edge and corner-sharing SrI7 pentagonal bipyramids. There are a spread of Sr(1)-I(1) bond distances ranging from 3.30-3.42 Å. There are a spread of Sr(1)-I(2) bond distances ranging from 3.38-3.46 Å. There are two inequivalent I sites.
