The compound described by CaCdPb crystallizes in the hexagonal P-62m space group. Ca(1) is bonded in a 11-coordinate geometry to six equivalent Cd(1), one Pb(1), and four equivalent Pb(2) atoms. Cd(1) is bonded in a 4-coordinate geometry to six equivalent Ca(1), two equivalent Pb(1), and two equivalent Pb(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted q6 geometry to three equivalent Ca(1) and six equivalent Cd(1) atoms. In the second Pb site, Pb(2) is bonded in a 9-coordinate geometry to six equivalent Ca(1) and three equivalent Cd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
