Dy(IrB)2 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Fddd space group. Dy(1) is bonded to four equivalent Ir(1) and four equivalent B(1) atoms to form distorted face-sharing DyB4Ir4 hexagonal bipyramids. Ir(1) is bonded in a 7-coordinate geometry to two equivalent Dy(1) and five equivalent B(1) atoms. B(1) is bonded in a 8-coordinate geometry to two equivalent Dy(1), five equivalent Ir(1), and one B(1) atom.
Dy(IrB)2 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Fddd space group. Dy(1) is bonded to four equivalent Ir(1) and four equivalent B(1) atoms to form distorted face-sharing DyB4Ir4 hexagonal bipyramids. There are two shorter (3.00 Å) and two longer (3.01 Å) Dy(1)-Ir(1) bond lengths. There are two shorter (2.80 Å) and two longer (2.81 Å) Dy(1)-B(1) bond lengths. Ir(1) is bonded in a 7-coordinate geometry to two equivalent Dy(1) and five equivalent B(1) atoms. There are a spread of Ir(1)-B(1) bond distances ranging from 2.15-2.37 Å. B(1) is bonded in a 8-coordinate geometry to two equivalent Dy(1), five equivalent Ir(1), and one B(1) atom. The B(1)-B(1) bond length is 1.87 Å.
