B Sb Sb Ir
IrBSb2 crystallizes in the monoclinic Cm space group. Ir(1) is bonded in a 4-coordinate geometry to one B(1) and eight equivalent Sb(1) atoms. The Ir(1)-B(1) bond length is 2.87 Å. There are a spread of Ir(1)-Sb(1) bond distances ranging from 2.47-3.27 Å. B(1) is bonded in a 5-coordinate geometry to one Ir(1) and four equivalent Sb(1) atoms. There are two shorter (2.47 Å) and two longer (2.63 Å) B(1)-Sb(1) bond lengths. Sb(1) is bonded in a 6-coordinate geometry to four equivalent Ir(1) and two equivalent B(1) atoms.
