LiPtSn crystallizes in the triclinic P1 space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Sn(1) atoms. There is one shorter (2.07 Å) and one longer (2.08 Å) Li(1)-Pt(1) bond length. There is one shorter (2.19 Å) and one longer (2.20 Å) Li(1)-Sn(1) bond length. Pt(1) is bonded in a 2-coordinate geometry to two equivalent Li(1) and two equivalent Sn(1) atoms. There is one shorter (2.48 Å) and one longer (2.80 Å) Pt(1)-Sn(1) bond length. Sn(1) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Pt(1) atoms.
