Materials Data on NaCu(IO3)3 by Materials Project
NaCu(O3I)3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.46–2.89 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six O2- atoms to form corner-sharing CuO6 octahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Cu–O bond distances ranging from 1.94–2.49 Å. In the second Cu2+ site, Cu2+ is bonded to six O2- atoms to form corner-sharing CuO6 octahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Cu–O bond distances ranging from 1.96–2.45 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+ and two I5+ atoms. There are one shorter (1.85 Å) and one longer (2.62 Å) O–I bond lengths. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Na1+ and one I5+ atom. The O–I bond length is 1.83 Å. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.81 Å. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+ and two I5+ atoms. There are one shorter (1.83 Å) and one longer (2.72 Å) O–I bond lengths. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Cu2+, and one I5+ atom. The O–I bond length is 1.86 Å. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Na1+, one Cu2+, and one I5+ atom. The O–I bond length is 1.87 Å. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Na1+, one Cu2+, and one I5+ atom. The O–I bond length is 1.87 Å. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two Cu2+, and one I5+ atom. The O–I bond length is 1.84 Å. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+ and one I5+ atom. The O–I bond length is 1.87 Å. There are three inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 5-coordinate geometry to four O2- atoms. In the second I5+ site, I5+ is bonded in a 6-coordinate geometry to four O2- atoms. In the third I5+ site, I5+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms.
