Materials Data on CaCdPb by Materials Project
CaCdPb crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ca is bonded in a 5-coordinate geometry to six equivalent Cd and five Pb atoms. There are two shorter (3.50 Å) and four longer (3.77 Å) Ca–Cd bond lengths. There are one shorter (3.34 Å) and four longer (3.36 Å) Ca–Pb bond lengths. Cd is bonded in a 4-coordinate geometry to six equivalent Ca and four Pb atoms. There are two shorter (3.00 Å) and two longer (3.11 Å) Cd–Pb bond lengths. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a distorted q6 geometry to three equivalent Ca and six equivalent Cd atoms. In the second Pb site, Pb is bonded in a 9-coordinate geometry to six equivalent Ca and three equivalent Cd atoms.
