Title: Materials Data on KIBr2O by Materials Project

Abstract

KOIBr2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent K sites. In the first K site, K is bonded in a 2-coordinate geometry to two equivalent O and three Br atoms. Both K–O bond lengths are 2.82 Å. There are a spread of K–Br bond distances ranging from 3.57–3.78 Å. In the second K site, K is bonded in a 2-coordinate geometry to two equivalent O and three Br atoms. Both K–O bond lengths are 2.82 Å. There are a spread of K–Br bond distances ranging from 3.57–3.79 Å. In the third K site, K is bonded in a 2-coordinate geometry to two equivalent O and five Br atoms. Both K–O bond lengths are 2.62 Å. There are a spread of K–Br bond distances ranging from 3.38–3.49 Å. In the fourth K site, K is bonded in a 2-coordinate geometry to two equivalent O and five Br atoms. Both K–O bond lengths are 2.62 Å. There are a spread of K–Br bond distances ranging from 3.39–3.49 Å. There are four inequivalent O sites. In the first O site, O is bonded in a trigonal non-coplanar geometry to two equivalent K and one Brmore » atom. The O–Br bond length is 1.76 Å. In the second O site, O is bonded in a trigonal non-coplanar geometry to two equivalent K and one Br atom. The O–Br bond length is 1.76 Å. In the third O site, O is bonded in a 4-coordinate geometry to two equivalent K and two Br atoms. There are one shorter (2.57 Å) and one longer (2.59 Å) O–Br bond lengths. In the fourth O site, O is bonded in a 2-coordinate geometry to two equivalent K and two Br atoms. There are one shorter (2.57 Å) and one longer (2.59 Å) O–Br bond lengths. There are four inequivalent I sites. In the first I site, I is bonded in a linear geometry to two Br atoms. Both I–Br bond lengths are 2.72 Å. In the second I site, I is bonded in a linear geometry to two Br atoms. Both I–Br bond lengths are 2.75 Å. In the third I site, I is bonded in a linear geometry to two Br atoms. Both I–Br bond lengths are 2.73 Å. In the fourth I site, I is bonded in a linear geometry to two Br atoms. Both I–Br bond lengths are 2.91 Å. There are eight inequivalent Br sites. In the first Br site, Br is bonded in a 4-coordinate geometry to two equivalent K, one O, and one I atom. In the second Br site, Br is bonded in a 1-coordinate geometry to two equivalent K, one O, and one I atom. In the third Br site, Br is bonded in a rectangular see-saw-like geometry to three K and one I atom. In the fourth Br site, Br is bonded in a rectangular see-saw-like geometry to three K and one I atom. In the fifth Br site, Br is bonded in a 5-coordinate geometry to three K, one O, and one I atom. In the sixth Br site, Br is bonded in a 5-coordinate geometry to three K, one O, and one I atom. In the seventh Br site, Br is bonded in a distorted single-bond geometry to one O and one I atom. In the eighth Br site, Br is bonded in a distorted single-bond geometry to one O and one I atom.« less
