Materials Data on K2SnBi by Materials Project
Abstract
K2SnBi crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 6-coordinate geometry to four equivalent Sn and four equivalent Bi atoms. There are two shorter (3.88 Å) and two longer (4.09 Å) K–Sn bond lengths. There are a spread of K–Bi bond distances ranging from 3.62–3.90 Å. In the second K site, K is bonded in a 2-coordinate geometry to four equivalent Sn and four equivalent Bi atoms. There are two shorter (3.95 Å) and two longer (4.05 Å) K–Sn bond lengths. There are a spread of K–Bi bond distances ranging from 3.66–3.89 Å. Sn is bonded to eight K, two equivalent Sn, and two equivalent Bi atoms to form a mixture of distorted corner, edge, and face-sharing SnK8Sn2Bi2 cuboctahedra. Both Sn–Sn bond lengths are 3.32 Å. Both Sn–Bi bond lengths are 3.08 Å. Bi is bonded in a 10-coordinate geometry to eight K and two equivalent Sn atoms.
