CaPt2Ga is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaPt2Ga clusters. Ca(1) is bonded in a single-bond geometry to one Ga(1) atom. The Ca(1)-Ga(1) bond length is 0.55 Å. Pt(1) is bonded in a single-bond geometry to one Ga(1) atom. The Pt(1)-Ga(1) bond length is 0.52 Å. Ga(1) is bonded in a trigonal non-coplanar geometry to one Ca(1) and two equivalent Pt(1) atoms.
