CaPtCu2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaPtCu2 clusters. Ca(1) is bonded in a single-bond geometry to one Pt(1) and one Cu(2) atom. The Ca(1)-Pt(1) bond length is 0.04 Å. The Ca(1)-Cu(2) bond length is 1.86 Å. Pt(1) is bonded in a single-bond geometry to one Ca(1) and one Cu(1) atom. The Pt(1)-Cu(1) bond length is 1.89 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted single-bond geometry to one Pt(1) atom. In the second Cu site, Cu(2) is bonded in a distorted single-bond geometry to one Ca(1) atom.
