BaPtAl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaPtAl clusters. Ba(1) is bonded in a distorted single-bond geometry to one Al(1) atom. The Ba(1)-Al(1) bond length is 2.35 Å. Pt(1) is bonded in a single-bond geometry to one Al(1) atom. The Pt(1)-Al(1) bond length is 0.46 Å. Al(1) is bonded in a distorted single-bond geometry to one Ba(1) and one Pt(1) atom.
