Materials Data on Pd(IO3)2 by Materials Project
Pd(O3I)2 crystallizes in the orthorhombic Pbca space group. The structure is two-dimensional and consists of two Pd(O3I)2 sheets oriented in the (0, 0, 1) direction. Pd2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.02 Å) and two longer (2.04 Å) Pd–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Pd2+ and one I5+ atom. The O–I bond length is 1.88 Å. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.83 Å. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pd2+ and one I5+ atom. The O–I bond length is 1.85 Å. I5+ is bonded in a 3-coordinate geometry to three O2- atoms.
