RbDyBr3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Br(2) and six equivalent Br(1) atoms. Dy(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing DyBr6 octahedra. The corner-sharing octahedral tilt angles range from 24-25°. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Dy(1) atoms. In the second Br site, Br(2) is bonded in a distorted square co-planar geometry to two equivalent Rb(1) and two equivalent Dy(1) atoms.
RbDyBr3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Br(2) and six equivalent Br(1) atoms. There is one shorter (3.53 Å) and one longer (3.56 Å) Rb(1)-Br(2) bond length. There are four shorter (3.63 Å) and two longer (3.87 Å) Rb(1)-Br(1) bond lengths. Dy(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing DyBr6 octahedra. The corner-sharing octahedral tilt angles range from 24-25°. Both Dy(1)-Br(2) bond lengths are 2.88 Å. All Dy(1)-Br(1) bond lengths are 2.88 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Dy(1) atoms. In the second Br site, Br(2) is bonded in a distorted square co-planar geometry to two equivalent Rb(1) and two equivalent Dy(1) atoms.
