KIr2Sb is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KIr2Sb clusters. K(1) is bonded in an L-shaped geometry to two equivalent Ir(1) atoms. Both K(1)-Ir(1) bond lengths are 0.82 Å. Ir(1) is bonded in a distorted L-shaped geometry to one K(1) and one Sb(1) atom. The Ir(1)-Sb(1) bond length is 0.82 Å. Sb(1) is bonded in an L-shaped geometry to two equivalent Ir(1) atoms.
