Materials Data on BaZnSn2 by Materials Project
BaZnSn2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ba is bonded in a 4-coordinate geometry to six equivalent Zn and eight Sn atoms. There are two shorter (3.63 Å) and four longer (4.02 Å) Ba–Zn bond lengths. There are a spread of Ba–Sn bond distances ranging from 3.62–4.03 Å. Zn is bonded in a 1-coordinate geometry to six equivalent Ba, two equivalent Zn, and one Sn atom. Both Zn–Zn bond lengths are 2.51 Å. The Zn–Sn bond length is 2.78 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Ba and four equivalent Sn atoms. There are two shorter (3.01 Å) and two longer (3.18 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a distorted single-bond geometry to four equivalent Ba, one Zn, and four equivalent Sn atoms.
