ZnAl2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Zn(1) is bonded to four equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with twelve equivalent Al(1)S6 octahedra. The corner-sharing octahedral tilt angles are 58°. Al(1) is bonded to six equivalent S(1) atoms to form AlS6 octahedra that share corners with six equivalent Zn(1)S4 tetrahedra and edges with six equivalent Al(1)S6 octahedra. S(1) is bonded to one Zn(1) and three equivalent Al(1) atoms to form a mixture of distorted edge and corner-sharing SAl3Zn trigonal pyramids.
