Ba2SrPt is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2SrPt clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one Pt(1) atom. The Ba(1)-Pt(1) bond length is 2.47 Å. In the second Ba site, Ba(2) is bonded in a single-bond geometry to one Sr(1) atom. The Ba(2)-Sr(1) bond length is 0.33 Å. Sr(1) is bonded in a linear geometry to one Ba(2) and one Pt(1) atom. The Sr(1)-Pt(1) bond length is 2.14 Å. Pt(1) is bonded in a linear geometry to one Ba(1) and one Sr(1) atom.
