GdIO crystallizes in the orthorhombic Fddd space group. Gd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent I(1) atoms. O(1) is bonded in a 4-coordinate geometry to four equivalent Gd(1) atoms. I(1) is bonded in a distorted square co-planar geometry to four equivalent Gd(1) atoms.
GdIO crystallizes in the orthorhombic Fddd space group. Gd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent I(1) atoms. There are two shorter (2.21 Å) and two longer (2.83 Å) Gd(1)-O(1) bond lengths. There are two shorter (3.17 Å) and two longer (3.38 Å) Gd(1)-I(1) bond lengths. O(1) is bonded in a 4-coordinate geometry to four equivalent Gd(1) atoms. I(1) is bonded in a distorted square co-planar geometry to four equivalent Gd(1) atoms.
