CaPt2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded in a 12-coordinate geometry to three equivalent Pt(1) and nine equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to six equivalent Ca(1) and six equivalent Pt(2) atoms to form a mixture of edge, corner, and face-sharing PtCa6Pt6 cuboctahedra. In the second Pt site, Pt(2) is bonded to six equivalent Ca(1), two equivalent Pt(1), and four equivalent Pt(2) atoms to form a mixture of edge, corner, and face-sharing PtCa6Pt6 cuboctahedra.
CaPt2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded in a 12-coordinate geometry to three equivalent Pt(1) and nine equivalent Pt(2) atoms. All Ca(1)-Pt(1) bond lengths are 3.17 Å. There are six shorter (3.17 Å) and three longer (3.20 Å) Ca(1)-Pt(2) bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to six equivalent Ca(1) and six equivalent Pt(2) atoms to form a mixture of edge, corner, and face-sharing PtCa6Pt6 cuboctahedra. All Pt(1)-Pt(2) bond lengths are 2.73 Å. In the second Pt site, Pt(2) is bonded to six equivalent Ca(1), two equivalent Pt(1), and four equivalent Pt(2) atoms to form a mixture of edge, corner, and face-sharing PtCa6Pt6 cuboctahedra. There are two shorter (2.67 Å) and two longer (2.74 Å) Pt(2)-Pt(2) bond lengths.
