Materials Data on Rb2Te(H6O5)2 by Materials Project
Rb2H10TeO9H2O crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two water molecules and one Rb2H10TeO9 ribbon oriented in the (0, 1, 0) direction. In the Rb2H10TeO9 ribbon, there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to one H1+ and seven O2- atoms. The Rb–H bond length is 3.04 Å. There are a spread of Rb–O bond distances ranging from 2.89–3.21 Å. In the second Rb1+ site, Rb1+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.84 Å) and one longer (2.89 Å) Rb–O bond lengths. There are ten 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 1.00 Å. In the second 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 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 0.99 Å. In the fifth 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 sixth 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 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 Rb1+ and one O2- atom. The H–O bond length is 1.00 Å. In the ninth 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 tenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. Te6+ is bonded to six O2- atoms to form edge-sharing TeO6 octahedra. There are a spread of Te–O bond distances ranging from 1.89–2.03 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Te6+ atom. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Rb1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to two H1+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Te6+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to two Rb1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+ and two equivalent Te6+ atoms. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+, one H1+, and one Te6+ atom. In the eighth O2- site, O2- is bonded in a water-like geometry to one Rb1+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+, one H1+, and one Te6+ atom.
