NaPt2Bi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaPt2Bi cluster. Na(1) is bonded in a single-bond geometry to one Pt(1) and one Bi(1) atom. The Na(1)-Pt(1) bond length is 2.91 Å. The Na(1)-Bi(1) bond length is 0.11 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to one Na(1) and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 0.39 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Pt(1) atom. Bi(1) is bonded in a single-bond geometry to one Na(1) atom.
