Title: Materials Data on KH(IO3)2 by Materials Project

Abstract

KH(IO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.03 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to one H1+ and eight O2- atoms. The K–H bond length is 2.87 Å. There are a spread of K–O bond distances ranging from 2.73–3.09 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 1.01 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one I5+ atom. The O–I bond length is 1.85 Å. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.82 Å) and one longermore » (2.72 Å) O–I bond lengths. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.82 Å) and one longer (2.66 Å) O–I bond lengths. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one I5+ atom. The O–I bond length is 1.81 Å. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.83 Å. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one H1+, and one I5+ atom. The O–I bond length is 1.99 Å. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one I5+ atom. The O–I bond length is 1.83 Å. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one H1+, and one I5+ atom. The O–I bond length is 1.94 Å. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.82 Å) and one longer (2.70 Å) O–I bond lengths. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.55 Å) O–I bond lengths. In the eleventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent K1+ and two I5+ atoms. There are one shorter (1.85 Å) and one longer (2.49 Å) O–I bond lengths. In the twelfth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one I5+ atom. The O–I bond length is 1.81 Å. There are four inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. In the second I5+ site, I5+ is bonded in a 3-coordinate geometry to three O2- atoms. In the third I5+ site, I5+ is bonded in a 6-coordinate geometry to five O2- atoms. In the fourth I5+ site, I5+ is bonded in a 6-coordinate geometry to six O2- atoms.« less
