Materials Data on K2CdPb by Materials Project
K2CdPb crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 4-coordinate geometry to two equivalent Cd and four equivalent Pb atoms. Both K–Cd bond lengths are 4.01 Å. There are a spread of K–Pb bond distances ranging from 3.79–3.91 Å. In the second K site, K is bonded in a 4-coordinate geometry to two equivalent Cd and four equivalent Pb atoms. Both K–Cd bond lengths are 4.03 Å. There are two shorter (3.78 Å) and two longer (3.94 Å) K–Pb bond lengths. Cd is bonded in a distorted linear geometry to four K and two equivalent Pb atoms. Both Cd–Pb bond lengths are 2.91 Å. Pb is bonded in a 10-coordinate geometry to eight K and two equivalent Cd atoms.
