The structure described by H2Pt(OH)6 crystallizes in the monoclinic Cc space group. Pt(1) is bonded in an octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are eight 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 single-bond geometry to one O(1) atom. In the third H site, H(3) is bonded in a linear geometry to one O(2) and one O(4) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one O(3) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one O(4) atom. In the seventh H site, H(7) is bonded in a distorted single-bond geometry to one O(5) atom. In the eighth H site, H(8) is bonded in a linear geometry to one O(5) and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Pt(1), one H(1), and one H(2) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one Pt(1), one H(3), and one H(4) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to one Pt(1), one H(1), and one H(5) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one Pt(1), one H(3), and one H(6) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Pt(1), one H(7), and one H(8) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Pt(1) and one H(8) atom. is represented by the CIF file [CIF]
