SrBrI is Cotunnite-derived structured and crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 7-coordinate geometry to four equivalent I(1) and three equivalent Br(1) atoms. I(1) is bonded to four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing ISr4 tetrahedra. Br(1) is bonded in a trigonal non-coplanar geometry to three equivalent Sr(1) atoms.
SrBrI is Cotunnite-derived structured and crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 7-coordinate geometry to four equivalent I(1) and three equivalent Br(1) atoms. There is one shorter (3.39 Å) and three longer (3.51 Å) Sr(1)-I(1) bond lengths. There is one shorter (3.07 Å) and two longer (3.12 Å) Sr(1)-Br(1) bond lengths.
