Title: Materials Data on Ir2(Se3Br2)3 by Materials Project

Abstract

Ir2(Se3Br2)3 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Ir5+ is bonded in an octahedral geometry to three Se+1.11- and three Br atoms. There are two shorter (2.41 Å) and one longer (2.42 Å) Ir–Se bond lengths. There are a spread of Ir–Br bond distances ranging from 2.55–2.57 Å. There are five inequivalent Se+1.11- sites. In the first Se+1.11- site, Se+1.11- is bonded in a 1-coordinate geometry to one Ir5+ and one Se+1.11- atom. The Se–Se bond length is 2.39 Å. In the second Se+1.11- site, Se+1.11- is bonded in a 1-coordinate geometry to one Ir5+ and one Se+1.11- atom. The Se–Se bond length is 2.39 Å. In the third Se+1.11- site, Se+1.11- is bonded in a 1-coordinate geometry to one Ir5+ and one Se+1.11- atom. The Se–Se bond length is 2.42 Å. In the fourth Se+1.11- site, Se+1.11- is bonded in a 4-coordinate geometry to two equivalent Se+1.11- and two equivalent Br atoms. Both Se–Br bond lengths are 3.34 Å. In the fifth Se+1.11- site, Se+1.11- is bonded in a distorted rectangular see-saw-like geometry to two Se+1.11- and two Br atoms. There are one shorter (3.17 Å) and one longer (3.51 Å) Se–Br bond lengths. Theremore » are three inequivalent Br sites. In the first Br site, Br is bonded in a distorted single-bond geometry to one Ir5+ and one Se+1.11- atom. In the second Br site, Br is bonded in a 1-coordinate geometry to one Ir5+ and one Se+1.11- atom. In the third Br site, Br is bonded in a 1-coordinate geometry to one Ir5+ and one Se+1.11- atom.« less
