The structure described by Ca5Pt2 is Zircon-derived structured and crystallizes in the monoclinic C2/c space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 2-coordinate geometry to three equivalent Pt(1) atoms. In the second Ca site, Ca(3) is bonded to four equivalent Pt(1) atoms to form distorted edge-sharing CaPt4 tetrahedra. In the third Ca site, Ca(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Ca(3), three equivalent Ca(1), and three equivalent Ca(2) atoms. is represented by the CIF card [CIF]
