KPt2Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KPt2Sn cluster. K(1) is bonded in a water-like geometry to one Pt(1) and one Sn(1) atom. The K(1)-Pt(1) bond length is 1.52 Å. The K(1)-Sn(1) bond length is 1.37 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one K(1) atom. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Sn(1) atom. The Pt(2)-Sn(1) bond length is 0.92 Å. Sn(1) is bonded in a bent 120 degrees geometry to one K(1) and one Pt(2) atom.
