YbZn2Sb2 crystallizes in the trigonal P-3m1 space group. Yb(1) is bonded to six equivalent Sb(1) atoms to form YbSb6 octahedra that share corners with twelve equivalent Zn(1)Sb4 tetrahedra, edges with six equivalent Yb(1)Sb6 octahedra, and edges with six equivalent Zn(1)Sb4 tetrahedra. Zn(1) is bonded to four equivalent Sb(1) atoms to form ZnSb4 tetrahedra that share corners with six equivalent Yb(1)Sb6 octahedra, corners with six equivalent Zn(1)Sb4 tetrahedra, edges with three equivalent Yb(1)Sb6 octahedra, and edges with three equivalent Zn(1)Sb4 tetrahedra. The corner-sharing octahedral tilt angles range from 19-54°. Sb(1) is bonded to three equivalent Yb(1) and four equivalent Zn(1) atoms to form a mixture of distorted corner and edge-sharing SbYb3Zn4 pentagonal bipyramids.

All Yb(1)-Sb(1) bond lengths are 3.17 Å. Zn(1) is bonded to four equivalent Sb(1) atoms to form ZnSb4 tetrahedra that share corners with six equivalent Yb(1)Sb6 octahedra, corners with six equivalent Zn(1)Sb4 tetrahedra, edges with three equivalent Yb(1)Sb6 octahedra, and edges with three equivalent Zn(1)Sb4 tetrahedra. The corner-sharing octahedral tilt angles range from 19-54°. There are three shorter (2.68 Å) and one longer (2.79 Å) Zn(1)-Sb(1) bond length. Sb(1) is bonded to three equivalent Yb(1) and four equivalent Zn(1) atoms to form a mixture of distorted corner and edge-sharing SbYb3Zn4 pentagonal bipyramids.
