The material structure described by Sr(H2O3)2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(1) and one O(3) atom. In the second H site, H(2) is bonded in a linear geometry to one O(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent Sr(1) and one H(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent Sr(1) and one H(2) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Sr(1), one H(1), and one H(2) atom. is represented by the CIF file [CIF]
