Materials Data on Ca5Pt2 by Materials Project
Ca5Pt2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Ca sites. In the first Ca site, Ca is bonded in a 2-coordinate geometry to three equivalent Pt atoms. There are a spread of Ca–Pt bond distances ranging from 2.89–3.50 Å. In the second Ca site, Ca is bonded to four equivalent Pt atoms to form distorted edge-sharing CaPt4 tetrahedra. There are two shorter (3.01 Å) and two longer (3.07 Å) Ca–Pt bond lengths. In the third Ca site, Ca is bonded in a 3-coordinate geometry to three equivalent Pt atoms. There are a spread of Ca–Pt bond distances ranging from 2.94–3.12 Å. Pt is bonded in a 7-coordinate geometry to eight Ca atoms.
