Co2PtSb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Co2PtSb cluster. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted T-shaped geometry to one Co(2), one Pt(1), and one Sb(1) atom. The Co(1)-Co(2) bond length is 0.26 Å. The Co(1)-Pt(1) bond length is 0.35 Å. The Co(1)-Sb(1) bond length is 0.58 Å. In the second Co site, Co(2) is bonded in a distorted L-shaped geometry to one Co(1) and one Pt(1) atom. The Co(2)-Pt(1) bond length is 0.26 Å. Pt(1) is bonded in a 3-coordinate geometry to one Co(1), one Co(2), and one Sb(1) atom. The Pt(1)-Sb(1) bond length is 0.58 Å. Sb(1) is bonded in a 2-coordinate geometry to one Co(1) and one Pt(1) atom.
