KPtSb2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KPtSb2 clusters. K(1) is bonded in a 3-coordinate geometry to one Pt(1) and two equivalent Sb(1) atoms. The K(1)-Pt(1) bond length is 2.08 Å. Both K(1)-Sb(1) bond lengths are 1.84 Å. Pt(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Sb(1) atoms. Both Pt(1)-Sb(1) bond lengths are 1.84 Å. Sb(1) is bonded in a 2-coordinate geometry to one K(1) and one Pt(1) atom.
