BaPt2Bi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaPt2Bi clusters. Ba(1) is bonded in a distorted L-shaped geometry to two equivalent Pt(1) atoms. Both Ba(1)-Pt(1) bond lengths are 2.18 Å. Pt(1) is bonded in a 1-coordinate geometry to one Ba(1) and one Bi(1) atom. The Pt(1)-Bi(1) bond length is 2.18 Å. Bi(1) is bonded in a distorted L-shaped geometry to two equivalent Pt(1) atoms.
