description: C4Te(BrF3)2 is Hg_xSn structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one C4Te(BrF3)2 cluster. there are eight inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a water-like geometry to two F1- atoms. Both C–F bond lengths are 1.33 Å. In the second C+2.50+ site, C+2.50+ is bonded in a bent 120 degrees geometry to two F1- atoms. Both C–F bond lengths are 1.33 Å. In the third C+2.50+ site, C+2.50+ is bonded in a distorted single-bond geometry to one Te2- and one F1- atom. The C–Te bond length is 2.16 Å. The C–F bond length is 1.35 Å. In the fourth C+2.50+ site, C+2.50+ is bonded in a bent 120 degrees geometry to two F1- atoms. There is one shorter (1.32 Å) and one longer (1.33 Å) C–F bond length. In the fifth C+2.50+ site, C+2.50+ is bonded in a bent 120 degrees geometry to two F1- atoms. There is one shorter (1.32 Å) and one longer (1.33 Å) C–F bond length. In the sixth C+2.50+ site, C+2.50+ is bonded in a distorted single-bond geometry to one Te2- and one F1- atom. The C–Te bond length is 2.16 Å. The C–F bond length is 1.36 Å. In the seventh C+2.50+ site, C+2.50+ is bonded in a distorted single-bond geometry to one Te2- and one F1- atom. The C–Te bond length is 2.15 Å. The C–F bond length is 1.35 Å. In the eighth C+2.50+ site, C+2.50+ is bonded in a distorted single-bond geometry to one Te2- and one F1- atom. The C–Te bond length is 2.16 Å. The C–F bond length is 1.35 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 4-coordinate geometry to two C+2.50+ and four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.66–3.49 Å. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to two C+2.50+ and three Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.62–3.26 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 1-coordinate geometry to two Te2- and three F1- atoms. There are a spread of Br–F bond distances ranging from 3.35–3.47 Å. In the second Br1- site, Br1- is bonded in a distorted single-bond geometry to one Te2- atom. In the third Br1- site, Br1- is bonded in a distorted single-bond geometry to one Te2- atom. In the fourth Br1- site, Br1- is bonded in a 1-coordinate geometry to three Te2- and four F1- atoms. There are a spread of Br–F bond distances ranging from 3.34–3.56 Å. There are twelve inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one C+2.50+ and one Br1- atom. In the second F1- site, F1- is bonded in a single-bond geometry to one C+2.50+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one C+2.50+ and one Br1- atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one C+2.50+ and one Br1- atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one C+2.50+ atom.
