Materials Data on PdI2 by Materials Project

PdI2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one PdI2 sheet oriented in the (1, 0, 0) direction. Pd2+ is bonded in a 4-coordinate geometry to five I1- atoms. There are a spread of Pd–I bond distances ranging from 2.63–3.44 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a water-like geometry to two equivalent Pd2+ atoms. In the second I1- site, I1- is bonded in a 3-coordinate geometry to three equivalent Pd2+ atoms.

Materials Data on PdI2 by Materials Project

PdI2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. The structure is one-dimensional and consists of two PdI2 ribbons oriented in the (1, 0, 0) direction. Pd2+ is bonded in a square co-planar geometry to four equivalent I1- atoms. All Pd–I bond lengths are 2.63 Å. I1- is bonded in an L-shaped geometry to two equivalent Pd2+ atoms.
