The material structure described by Sr(H2O3)2 crystallizes in the monoclinic Cc space group. Sr(1) is bonded in a 10-coordinate geometry to one H(2), one O(1), one O(5), one O(6), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one Sr(1) and one O(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth H site, H(4) is bonded in a linear geometry to one O(1) and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Sr(1), one H(1), and one H(4) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent Sr(1), one H(3), and one O(4) atom. In the third O site, O(3) is bonded in a single-bond geometry to two equivalent Sr(1) and one H(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sr(1) and one O(2) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Sr(1), one H(4), and one O(6) atom. In the sixth O site, O(6) is bonded in a 1-coordinate geometry to one Sr(1) and one O(5) atom. is represented by the CIF card [CIF]
