Sr(IO3)2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one I(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent Sr(1) and one I(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one I(1) atom. I(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom.
Sr(IO3)2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. Both Sr(1)-O(1) bond lengths are 2.64 Å. There are two shorter (2.67 Å) and two longer (3.07 Å) Sr(1)-O(2) bond lengths. There are two shorter (2.62 Å) and two longer (2.76 Å) Sr(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one I(1) atom. The O(1)-I(1) bond length is 1.81 Å. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent Sr(1) and one I(1) atom. The O(2)-I(1) bond length is 1.83 Å. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one I(1) atom. The O(3)-I(1) bond length is 1.81 Å. I(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom.
