PtBa(Re)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two rhenium molecules and two PtBa clusters. In each PtBa cluster, Ba(1) is bonded in a distorted single-bond geometry to one Pt(1) atom. The Ba(1)-Pt(1) bond length is 1.37 Å. Pt(1) is bonded in a single-bond geometry to one Ba(1) atom.
