SrCaI4 crystallizes in the tetragonal I4_1/a space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent I(1) atoms. Ca(1) is bonded in a tetrahedral geometry to four equivalent I(1) atoms. I(1) is bonded in a trigonal planar geometry to two equivalent Sr(1) and one Ca(1) atom.
SrCaI4 crystallizes in the tetragonal I4_1/a space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent I(1) atoms. There are four shorter (3.43 Å) and four longer (3.53 Å) Sr(1)-I(1) bond lengths. Ca(1) is bonded in a tetrahedral geometry to four equivalent I(1) atoms. All Ca(1)-I(1) bond lengths are 3.03 Å. I(1) is bonded in a trigonal planar geometry to two equivalent Sr(1) and one Ca(1) atom.
