Materials Data on K3Bi by Materials Project

Abstract

K3Bi crystallizes in the hexagonal P6_3cm space group. The structure is three-dimensional. there are four inequivalent K sites. In the first K site, K is bonded in a trigonal planar geometry to three equivalent Bi atoms. All K–Bi bond lengths are 3.61 Å. In the second K site, K is bonded in a trigonal planar geometry to three equivalent Bi atoms. All K–Bi bond lengths are 3.62 Å. In the third K site, K is bonded in a 3-coordinate geometry to three equivalent Bi atoms. There are one shorter (3.67 Å) and two longer (3.96 Å) K–Bi bond lengths. In the fourth K site, K is bonded in a 2-coordinate geometry to two equivalent Bi atoms. There are one shorter (3.68 Å) and one longer (3.88 Å) K–Bi bond lengths. Bi is bonded in a 8-coordinate geometry to eight K atoms.
