Abstract

Os2Tl4COBr4F6CO crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four formaldehyde molecules and one Os2Tl4COBr4F6 sheet oriented in the (-1, 0, 2) direction. In the Os2Tl4COBr4F6 sheet, there are two inequivalent Os1+ sites. In the first Os1+ site, Os1+ is bonded in a 5-coordinate geometry to two Br1- and three F1- atoms. There are one shorter (2.48 Å) and one longer (2.49 Å) Os–Br bond lengths. There are two shorter (2.02 Å) and one longer (2.12 Å) Os–F bond lengths. In the second Os1+ site, Os1+ is bonded in a 5-coordinate geometry to two Br1- and three F1- atoms. Both Os–Br bond lengths are 2.48 Å. There are a spread of Os–F bond distances ranging from 2.02–2.10 Å. There are four inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 4-coordinate geometry to four F1- atoms. There are a spread of Tl–F bond distances ranging from 2.66–2.97 Å. In the second Tl1+ site, Tl1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Tl–F bond distances ranging from 2.76–3.10 Å. In the third Tl1+ site, Tl1+ is bonded in a 2-coordinate geometry to two F1- atoms. Both Tl–F bond lengths are 2.91 Å. In the fourth Tl1+ site, Tl1+ is bonded in a 1-coordinate geometry to one O2- and four F1- atoms. The Tl–O bond length is 3.19 Å. There are a spread of Tl–F bond distances ranging from 2.67–2.98 Å. C4+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.18 Å. O2- is bonded in a distorted single-bond geometry to one Tl1+ and one C4+ atom. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted single-bond geometry to one Os1+ atom. In the second Br1- site, Br1- is bonded in a distorted single-bond geometry to one Os1+ atom. In the third Br1- site, Br1- is bonded in a 1-coordinate geometry to one Os1+ atom. In the fourth Br1- site, Br1- is bonded in a 1-coordinate geometry to one Os1+ atom. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to one Os1+ and three Tl1+ atoms. In the second F1- site, F1- is bonded in a distorted single-bond geometry to one Os1+ and three Tl1+ atoms. In the third F1- site, F1- is bonded in a 1-coordinate geometry to one Os1+ and three Tl1+ atoms. In the fourth F1- site, F1- is bonded in a 1-coordinate geometry to one Os1+ and three Tl1+ atoms. In the fifth F1- site, F1- is bonded in a 1-coordinate geometry to one Os1+ and two equivalent Tl1+ atoms. In the sixth F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to one Os1+ and two Tl1+ atoms.
