Materials Data on AgH8O5 by Materials Project
Ag(H3O2)2H2O crystallizes in the orthorhombic P2_12_12_1 space group. The structure is one-dimensional and consists of four water molecules and two Ag(H3O2)2 ribbons oriented in the (1, 0, 0) direction. In each Ag(H3O2)2 ribbon, Ag2+ is bonded to six O2- atoms to form distorted face-sharing AgO6 octahedra. There are a spread of Ag–O bond distances ranging from 2.21–2.72 Å. There are six 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 0.98 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.62 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth 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 fifth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.02 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Ag2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag2+ and one H1+ atom.
