Sr3SbI3 crystallizes in the cubic I4_132 space group. Sr(1) is bonded to two equivalent Sb(1) and four equivalent I(1) atoms to form a mixture of corner and edge-sharing SrSb2I4 octahedra. The corner-sharing octahedral tilt angles range from 3-4°. Sb(1) is bonded to six equivalent Sr(1) atoms to form edge-sharing SbSr6 octahedra. I(1) is bonded in a rectangular see-saw-like geometry to four equivalent Sr(1) atoms.

The corner-sharing octahedral tilt angles range from 3-4°. Both Sr(1)-Sb(1) bond lengths are 3.26 Å. There are two shorter (3.39 Å) and two longer (3.46 Å) Sr(1)-I(1) bond lengths. Sb(1) is bonded to six equivalent Sr(1) atoms to form edge-sharing SbSr6 octahedra. I(1) is bonded in a rectangular see-saw-like geometry to four equivalent Sr(1) atoms.
