Materials Data on CoAs3 by Materials Project
CoAs3 is Skutterudite structured and crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Co1+ is bonded to six equivalent As+0.33- atoms to form corner-sharing CoAs6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Co–As bond lengths are 2.35 Å. As+0.33- is bonded in a distorted bent 120 degrees geometry to two equivalent Co1+ and two equivalent As+0.33- atoms. There are one shorter (2.51 Å) and one longer (2.63 Å) As–As bond lengths.
