CoAsS is Spinel-like structured and crystallizes in the cubic P2_13 space group. Co(1) is bonded to three equivalent As(1) and three equivalent S(1) atoms to form CoAs3S3 octahedra that share corners with twelve equivalent Co(1)As3S3 octahedra, corners with three equivalent As(1)Co3S tetrahedra, and corners with three equivalent S(1)Co3As tetrahedra. The corner-sharing octahedral tilt angles are 64°. As(1) is bonded to three equivalent Co(1) and one S(1) atom to form AsCo3S tetrahedra that share corners with three equivalent Co(1)As3S3 octahedra, corners with six equivalent As(1)Co3S tetrahedra, and corners with nine equivalent S(1)Co3As tetrahedra. The corner-sharing octahedral tilt angles are 79°. S(1) is bonded to three equivalent Co(1) and one As(1) atom to form SCo3As tetrahedra that share corners with three equivalent Co(1)As3S3 octahedra, corners with six equivalent S(1)Co3As tetrahedra, and corners with nine equivalent As(1)Co3S tetrahedra. The corner-sharing octahedral tilt angles are 79°.
