CoAs3 is Skutterudite structured and crystallizes in the cubic Im-3 space group. Co(1) is bonded to six equivalent As(1) atoms to form corner-sharing CoAs6 octahedra. The corner-sharing octahedral tilt angles are 57°. As(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Co(1) and two equivalent As(1) atoms.
CoAs3 is Skutterudite structured and crystallizes in the cubic Im-3 space group. Co(1) is bonded to six equivalent As(1) atoms to form corner-sharing CoAs6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Co(1)-As(1) bond lengths are 2.33 Å. As(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Co(1) and two equivalent As(1) atoms. There is one shorter (2.47 Å) and one longer (2.60 Å) As(1)-As(1) bond length.
