Materials Data on Ag2H16O9 by Materials Project
(Ag2H15O8)2H2O2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four water molecules and two Ag2H15O8 ribbons oriented in the (0, 0, 1) direction. In each Ag2H15O8 ribbon, there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.43–2.67 Å. In the second Ag1+ site, Ag1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.41–2.93 Å. There are fifteen inequivalent H1+ sites. In the first 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 second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.61 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 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifth 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 sixth 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 seventh 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 eighth 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 ninth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom.

In the twelfth 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 thirteenth 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 fourteenth 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 fifteenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one Ag1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one Ag1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to two Ag1+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to two Ag1+ and two H1+ atoms.
