Materials Data on ZnCdSb2 by Materials Project

ZnCdSb2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Cd2+ is bonded to four Sb2- atoms to form distorted CdSb4 tetrahedra that share corners with four equivalent ZnSb4 tetrahedra, corners with six equivalent CdSb4 tetrahedra, and an edgeedge with one ZnSb4 tetrahedra. There are a spread of Cd–Sb bond distances ranging from 2.80–3.12 Å. Zn2+ is bonded to four Sb2- atoms to form distorted ZnSb4 tetrahedra that share corners with four equivalent CdSb4 tetrahedra, corners with six equivalent ZnSb4 tetrahedra, and an edgeedge with one CdSb4 tetrahedra. There are a spread of Zn–Sb bond distances ranging from 2.72–3.04 Å. There are two inequivalent Sb2- sites. In the first Sb2- site, Sb2- is bonded in a 5-coordinate geometry to three equivalent Cd2+, one Zn2+, and one Sb2- atom. The Sb–Sb bond length is 2.86 Å. In the second Sb2- site, Sb2- is bonded in a 5-coordinate geometry to one Cd2+, three equivalent Zn2+, and one Sb2- atom.
