Materials Data on CoBrO by Materials Project
CoOBr crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of two CoOBr sheets oriented in the (0, 0, 1) direction. there are four inequivalent Co3+ sites. In the first Co3+ site, Co3+ is bonded in a 6-coordinate geometry to three O2- and three Br1- atoms. There are a spread of Co–O bond distances ranging from 1.90–2.00 Å. There are a spread of Co–Br bond distances ranging from 2.59–2.75 Å. In the second Co3+ site, Co3+ is bonded in a 6-coordinate geometry to three O2- and three Br1- atoms. There are a spread of Co–O bond distances ranging from 1.90–1.99 Å. There are a spread of Co–Br bond distances ranging from 2.60–2.75 Å. In the third Co3+ site, Co3+ is bonded in a 6-coordinate geometry to three O2- and three Br1- atoms. There are a spread of Co–O bond distances ranging from 1.90–1.99 Å. There are a spread of Co–Br bond distances ranging from 2.61–2.77 Å. In the fourth Co3+ site, Co3+ is bonded in a 6-coordinate geometry to three O2- and three Br1- atoms. There are a spread of Co–O bond distances ranging from 1.90–1.99 Å. There are a spread of Co–Br bond distances ranging from 2.61–2.76 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Co3+ atoms. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Co3+ atoms. In the third O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Co3+ atoms. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Co3+ atoms. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 3-coordinate geometry to three Co3+ atoms. In the second Br1- site, Br1- is bonded in a 3-coordinate geometry to three Co3+ atoms. In the third Br1- site, Br1- is bonded in a 3-coordinate geometry to three Co3+ atoms. In the fourth Br1- site, Br1- is bonded in a 3-coordinate geometry to three Co3+ atoms.
