The material structure described by Cr(GaS2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. Cr(1) is bonded to four equivalent S(1) atoms to form CrS4 tetrahedra that share corners with twelve equivalent Ga(1)S6 octahedra. The corner-sharing octahedral tilt angles are 55°. Ga(1) is bonded to six equivalent S(1) atoms to form GaS6 octahedra that share corners with six equivalent Cr(1)S4 tetrahedra and edges with six equivalent Ga(1)S6 octahedra. S(1) is bonded in a distorted rectangular see-saw-like geometry to one Cr(1) and three equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
