Materials Data on Re(TeBr2)2 by Materials Project
Re(TeBr2)2 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Re7+ is bonded in a 6-coordinate geometry to four Te+1.50- and two Br1- atoms. There are a spread of Re–Te bond distances ranging from 2.64–2.78 Å. There are one shorter (2.67 Å) and one longer (2.68 Å) Re–Br bond lengths. There are two inequivalent Te+1.50- sites. In the first Te+1.50- site, Te+1.50- is bonded in a 2-coordinate geometry to one Re7+ and four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.59–2.92 Å. In the second Te+1.50- site, Te+1.50- is bonded in a 10-coordinate geometry to three equivalent Re7+ and seven Br1- atoms. There are a spread of Te–Br bond distances ranging from 3.48–3.84 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted single-bond geometry to three Te+1.50- atoms. In the second Br1- site, Br1- is bonded in a 1-coordinate geometry to one Re7+ and three Te+1.50- atoms. In the third Br1- site, Br1- is bonded in a 1-coordinate geometry to one Re7+ and three Te+1.50- atoms. In the fourth Br1- site, Br1- is bonded in a distorted single-bond geometry to two Te+1.50- atoms.
