The structure described by Sr2PtH8O8 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 9-coordinate geometry to one H(4), two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Pt(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) 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 distorted linear geometry to one O(2) and one O(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(3) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one Sr(1) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Sr(1), one H(2), and one H(4) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1), one Pt(1), and one H(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Sr(1), one Pt(1), and one H(2) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Sr(1), one Pt(1), and one H(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
