Materials Data on Te2PdBr6 by Materials Project
PdTe2Br6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four PdTe2Br6 clusters. Pd4+ is bonded in an L-shaped geometry to two Br1- atoms. There are one shorter (2.51 Å) and one longer (2.58 Å) Pd–Br bond lengths. There are two inequivalent Te1+ sites. In the first Te1+ site, Te1+ is bonded in a distorted rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.58–3.07 Å. In the second Te1+ site, Te1+ is bonded in a 4-coordinate geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.53–3.35 Å. There are six inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Te1+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Te1+ atom. In the third Br1- site, Br1- is bonded in a distorted L-shaped geometry to one Pd4+ and one Te1+ atom. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one Te1+ atom. In the fifth Br1- site, Br1- is bonded in a distorted single-bond geometry to two Te1+ atoms. In the sixth Br1- site, Br1- is bonded in a 1-coordinate geometry to one Pd4+ and two Te1+ atoms.
