Materials Data on Ag2Te(H2O3)2 by Materials Project

Abstract

Ag2Te(H2O3)2 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Ag1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.26–2.65 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.64 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.59 Å) H–O bond length. Te6+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ag1+, one H1+, and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag1+, one H1+, and one Te6+ atom. In the third O2- site, O2- is bonded to one Ag1+, two H1+, and one Te6+ atom to form distorted corner-sharing OAgTeH2 tetrahedra.
