RbDyI3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent I(2) and six equivalent I(1) atoms. Dy(1) is bonded to two equivalent I(2) and four equivalent I(1) atoms to form corner-sharing DyI6 octahedra. The corner-sharing octahedral tilt angles range from 27-28°. There are two inequivalent I sites. In the first I site, I(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Dy(1) atoms. In the second I site, I(2) is bonded in a distorted square co-planar geometry to two equivalent Rb(1) and two equivalent Dy(1) atoms.
RbDyI3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent I(2) and six equivalent I(1) atoms. There is one shorter (3.71 Å) and one longer (3.72 Å) Rb(1)-I(2) bond length. There are a spread of Rb(1)-I(1) bond distances ranging from 3.78-4.14 Å. Dy(1) is bonded to two equivalent I(2) and four equivalent I(1) atoms to form corner-sharing DyI6 octahedra. The corner-sharing octahedral tilt angles range from 27-28°. Both Dy(1)-I(2) bond lengths are 3.08 Å. All Dy(1)-I(1) bond lengths are 3.09 Å. There are two inequivalent I sites. In the first I site, I(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Dy(1) atoms. In the second I site, I(2) is bonded in a distorted square co-planar geometry to two equivalent Rb(1) and two equivalent Dy(1) atoms.
