Materials Data on InTe14(IrBr8)2 by Materials Project
(Ir)2InBr4(Te)7(Te2Br3)2(TeBr2)3 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four iridium molecules, fourteen tellurium molecules, two InBr4 clusters, two Te2Br3 clusters, and two TeBr2 clusters. In each InBr4 cluster, In3+ is bonded in a tetrahedral geometry to four Br1- atoms. There are a spread of In–Br bond distances ranging from 2.54–2.57 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the third Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In each Te2Br3 cluster, there are four inequivalent Te+0.29+ sites. In the first Te+0.29+ site, Te+0.29+ is bonded in a 1-coordinate geometry to one Br1- atom. The Te–Br bond length is 3.39 Å. In the second Te+0.29+ site, Te+0.29+ is bonded in a distorted single-bond geometry to one Br1- atom. The Te–Br bond length is 3.45 Å. In the third Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.64–2.98 Å. In the fourth Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.64–2.98 Å. There are six inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to three Te+0.29+ atoms. In the third Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the fourth Br1- site, Br1- is bonded in a 2-coordinate geometry to three Te+0.29+ atoms. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the sixth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In each TeBr2 cluster, there are three inequivalent Te+0.29+ sites. In the first Te+0.29+ site, Te+0.29+ is bonded in a single-bond geometry to one Br1- atom. The Te–Br bond length is 3.33 Å. In the second Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are two shorter (2.67 Å) and two longer (2.94 Å) Te–Br bond lengths. In the third Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.64–3.03 Å. There are six inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to two Te+0.29+ atoms. In the third Br1- site, Br1- is bonded in a 3-coordinate geometry to three Te+0.29+ atoms. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom.
