Materials Data on Te7RuI6 by Materials Project

Abstract

Ru(Te)2Te5I6 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two ruthenium molecules, four tellurium molecules, and one Te5I6 cluster. In the Te5I6 cluster, there are five inequivalent Te+0.57+ sites. In the first Te+0.57+ site, Te+0.57+ is bonded in a distorted bent 120 degrees geometry to two I1- atoms. There are one shorter (3.43 Å) and one longer (3.68 Å) Te–I bond lengths. In the second Te+0.57+ site, Te+0.57+ is bonded in a bent 120 degrees geometry to two I1- atoms. There are one shorter (3.50 Å) and one longer (3.56 Å) Te–I bond lengths. In the third Te+0.57+ site, Te+0.57+ is bonded in a 1-coordinate geometry to one I1- atom. The Te–I bond length is 3.58 Å. In the fourth Te+0.57+ site, Te+0.57+ is bonded in a rectangular see-saw-like geometry to four I1- atoms. There are a spread of Te–I bond distances ranging from 2.97–3.17 Å. In the fifth Te+0.57+ site, Te+0.57+ is bonded in a rectangular see-saw-like geometry to four I1- atoms. There are a spread of Te–I bond distances ranging from 2.93–3.32 Å. There are six inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted water-like geometry to two Te+0.57+ atoms. In the second I1- site, I1- is bonded in a 1-coordinate geometry to two Te+0.57+ atoms. In the third I1- site, I1- is bonded in a 2-coordinate geometry to two Te+0.57+ atoms. In the fourth I1- site, I1- is bonded in a 2-coordinate geometry to three Te+0.57+ atoms. In the fifth I1- site, I1- is bonded in a single-bond geometry to two Te+0.57+ atoms. In the sixth I1- site, I1- is bonded in a 1-coordinate geometry to two Te+0.57+ atoms.
