Materials Data on K3In(IO3)6 by Materials Project

K3In(O3I)6 crystallizes in the triclinic P-1 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 2.73–3.18 Å. In the second K1+ site, K1+ is bonded in a distorted hexagonal bipyramidal geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.85–3.14 Å. In3+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of In–O bond distances ranging from 2.17–2.24 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one I5+ atom. The O–I bond length is 1.83 Å.
