La(IO3)3 crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one La(IO3)3 sheet oriented in the (0, 0, 1) direction. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.53–3.03 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one La3+, one O2-, and two I5+ atoms. The O–O bond length is 1.37 Å. There are one shorter (2.54 Å) and one longer (2.77 Å) O–I bond lengths. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one La3+ and two equivalent I5+ atoms. Both O–I bond lengths are 2.21 Å. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one La3+ and two equivalent I5+ atoms. Both O–I bond lengths are 2.15 Å. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one La3+ and one I5+ atom. The O–I bond length is 1.87 Å. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 5-coordinate geometry to five O2- atoms. In the second I5+ site, I5+ is bonded in a distorted water-like geometry to six O2- atoms.
