description: U2H14S2O19 crystallizes in the orthorhombic Pca2_1 space group. The structure is one-dimensional and consists of four U2H14S2O19 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with three SO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.80–2.45 Å. In the second U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with three SO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.80–2.45 Å. There are fourteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å.

In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three UO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.46–1.51 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three UO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.47–1.50 Å. There are nineteen inequivalent O2- sites.
