Materials Data on KH(IO3)2 by Materials Project
KH(IO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.76–3.21 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.22 Å. In the second H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.22 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.82 Å. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+, one H1+, and one I5+ atom. The O–I bond length is 1.89 Å. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one I5+ atom. The O–I bond length is 1.82 Å. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and two I5+ atoms. There are one shorter (1.83 Å) and one longer (2.67 Å) O–I bond lengths. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one I5+ atom. The O–I bond length is 1.84 Å. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one H1+, and one I5+ atom. The O–I bond length is 1.88 Å. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 3-coordinate geometry to four O2- atoms. In the second I5+ site, I5+ is bonded in a 6-coordinate geometry to three O2- atoms.
