CdZnBr is half-Heusler structured and crystallizes in the trigonal R3m space group. Cd(1) is bonded to four equivalent Zn(1) atoms to form CdZn4 tetrahedra that share corners with four equivalent Br(1)Zn4 tetrahedra, corners with twelve equivalent Cd(1)Zn4 tetrahedra, and edges with six equivalent Br(1)Zn4 tetrahedra. There is one shorter (2.98 Å) and three longer (3.05 Å) Cd(1)-Zn(1) bond lengths. Zn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Cd(1) and four equivalent Br(1) atoms. There are three shorter (3.02 Å) and one longer (3.05 Å) Zn(1)-Br(1) bond length. Br(1) is bonded to four equivalent Zn(1) atoms to form BrZn4 tetrahedra that share corners with four equivalent Cd(1)Zn4 tetrahedra, corners with twelve equivalent Br(1)Zn4 tetrahedra, and edges with six equivalent Cd(1)Zn4 tetrahedra.
