Ca Ru Ru Pt
CaRu2Pt is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaRu2Pt clusters. Ca(1) is bonded in a single-bond geometry to two equivalent Ru(1) and one Pt(1) atom. Both Ca(1)-Ru(1) bond lengths are 0.76 Å. The Ca(1)-Pt(1) bond length is 0.22 Å. Ru(1) is bonded in a 2-coordinate geometry to one Ca(1) and one Ru(1) atom. The Ru(1)-Ru(1) bond length is 0.22 Å. Pt(1) is bonded in a single-bond geometry to one Ca(1) atom.
