Ba Ba Pt Pt Pt
Ba2Pt3 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2Pt3 clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one Pt(2) atom. The Ba(1)-Pt(2) bond length is 1.25 Å. In the second Ba site, Ba(2) is bonded in a single-bond geometry to one Pt(1) atom. The Ba(2)-Pt(1) bond length is 0.46 Å. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Ba(2) and one Pt(3) atom. The Pt(1)-Pt(3) bond length is 0.78 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Ba(1) and one Pt(3) atom. The Pt(2)-Pt(3) bond length is 1.16 Å. In the third Pt site, Pt(3) is bonded in a linear geometry to one Pt(1) and one Pt(2) atom.
