Materials Data on GdIO by Materials Project
GdIO crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Gd3+ is bonded in a 2-coordinate geometry to four equivalent O2- and four equivalent I1- atoms. There are two shorter (2.22 Å) and two longer (2.86 Å) Gd–O bond lengths. There are two shorter (3.19 Å) and two longer (3.40 Å) Gd–I bond lengths. O2- is bonded in a 2-coordinate geometry to four equivalent Gd3+ and two equivalent I1- atoms. Both O–I bond lengths are 3.36 Å. I1- is bonded in a 6-coordinate geometry to four equivalent Gd3+ and two equivalent O2- atoms.
