GaZnSeAs is Stannite-like structured and crystallizes in the trigonal R3m space group. Zn(1) is bonded to one As(1) and three equivalent Se(1) atoms to form ZnAsSe3 tetrahedra that share corners with six equivalent Zn(1)AsSe3 tetrahedra and corners with six equivalent Ga(1)As3Se tetrahedra. Ga(1) is bonded to three equivalent As(1) and one Se(1) atom to form GaAs3Se tetrahedra that share corners with six equivalent Zn(1)AsSe3 tetrahedra and corners with six equivalent Ga(1)As3Se tetrahedra. As(1) is bonded to one Zn(1) and three equivalent Ga(1) atoms to form AsZnGa3 tetrahedra that share corners with six equivalent As(1)ZnGa3 tetrahedra and corners with six equivalent Se(1)Zn3Ga tetrahedra. Se(1) is bonded to three equivalent Zn(1) and one Ga(1) atom to form SeZn3Ga tetrahedra that share corners with six equivalent As(1)ZnGa3 tetrahedra and corners with six equivalent Se(1)Zn3Ga tetrahedra.
