Eu(IrB)2 is alpha Pu-derived structured and crystallizes in the orthorhombic Fddd space group. Eu(1) is bonded in a 14-coordinate geometry to eight equivalent Ir(1) and six equivalent B(1) atoms. Ir(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and four equivalent B(1) atoms. B(1) is bonded in a 4-coordinate geometry to three equivalent Eu(1) and four equivalent Ir(1) atoms.
Eu(IrB)2 is alpha Pu-derived structured and crystallizes in the orthorhombic Fddd space group. Eu(1) is bonded in a 14-coordinate geometry to eight equivalent Ir(1) and six equivalent B(1) atoms. There are four shorter (3.07 Å) and four longer (3.32 Å) Eu(1)-Ir(1) bond lengths. There are two shorter (3.04 Å) and four longer (3.15 Å) Eu(1)-B(1) bond lengths. Ir(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and four equivalent B(1) atoms. There are two shorter (2.09 Å) and two longer (2.16 Å) Ir(1)-B(1) bond lengths. B(1) is bonded in a 4-coordinate geometry to three equivalent Eu(1) and four equivalent Ir(1) atoms.
