Materials Data on Mg(ZnSb)2 by Materials Project
Mg(ZnSb)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent Sb3- atoms to form MgSb6 octahedra that share corners with twelve equivalent ZnSb4 tetrahedra, edges with six equivalent MgSb6 octahedra, and edges with six equivalent ZnSb4 tetrahedra. All Mg–Sb bond lengths are 3.05 Å. Zn2+ is bonded to four equivalent Sb3- atoms to form ZnSb4 tetrahedra that share corners with six equivalent MgSb6 octahedra, corners with six equivalent ZnSb4 tetrahedra, edges with three equivalent MgSb6 octahedra, and edges with three equivalent ZnSb4 tetrahedra. The corner-sharing octahedra tilt angles range from 11–56°. There are three shorter (2.74 Å) and one longer (2.80 Å) Zn–Sb bond lengths. Sb3- is bonded to three equivalent Mg2+ and four equivalent Zn2+ atoms to form a mixture of distorted edge and corner-sharing SbMg3Zn4 pentagonal bipyramids.
