The material structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
