Materials Data on BaZnBi2 by Materials Project

BaZnBi2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are four inequivalent Ba sites. In the first Ba site, Ba is bonded in a 12-coordinate geometry to eight Bi atoms. There are four shorter (3.62 Å) and four longer (3.72 Å) Ba–Bi bond lengths. In the second Ba site, Ba is bonded in a 12-coordinate geometry to eight Bi atoms. There are four shorter (3.62 Å) and four longer (3.72 Å) Ba–Bi bond lengths. In the third Ba site, Ba is bonded in a 12-coordinate geometry to eight Bi atoms. There are four shorter (3.62 Å) and four longer (3.72 Å) Ba–Bi bond lengths. In the fourth Ba site, Ba is bonded in a 12-coordinate geometry to eight Bi atoms. There are four shorter (3.62 Å) and four longer (3.72 Å) Ba–Bi bond lengths. Zn is bonded to four Bi atoms to form a mixture of edge and corner-sharing ZnBi4 tetrahedra. All Zn–Bi bond lengths are 2.90 Å. There are eight inequivalent Bi sites. In the first Bi site, Bi is bonded in a distorted body-centered cubic geometry to four Ba and four equivalent Bi atoms. All Bi–Bi bond lengths are 3.31 Å.
