IrCr(B)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two 14452-61-0 molecules and two IrCr clusters. In each IrCr cluster, Cr(1) is bonded in a single-bond geometry to one Ir(1) atom. The Cr(1)-Ir(1) bond length is 0.58 Å. Ir(1) is bonded in a single-bond geometry to one Cr(1) atom.
