YbOI2 crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded in a distorted water-like geometry to two equivalent O(1) and three equivalent I(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to two equivalent Yb(1) and one I(2) atom. There are two inequivalent I sites. In the first I site, I(2) is bonded in a distorted single-bond geometry to one O(1) atom. In the second I site, I(1) is bonded in a distorted T-shaped geometry to three equivalent Yb(1) atoms.
YbOI2 crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded in a distorted water-like geometry to two equivalent O(1) and three equivalent I(1) atoms. There is one shorter (2.20 Å) and one longer (2.21 Å) Yb(1)-O(1) bond length. All Yb(1)-I(1) bond lengths are 3.33 Å. O(1) is bonded in a distorted trigonal planar geometry to two equivalent Yb(1) and one I(2) atom. The O(1)-I(2) bond length is 2.06 Å. There are two inequivalent I sites. In the first I site, I(2) is bonded in a distorted single-bond geometry to one O(1) atom. In the second I site, I(1) is bonded in a distorted T-shaped geometry to three equivalent Yb(1) atoms.
