Title: Materials Data on CoAs2 by Materials Project

Abstract

CoAs2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Co4+ is bonded to six equivalent As2- atoms to form a mixture of edge and corner-sharing CoAs6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are two shorter (2.36 Å) and four longer (2.37 Å) Co–As bond lengths. As2- is bonded in a 4-coordinate geometry to three equivalent Co4+ and one As2- atom. The As–As bond length is 2.52 Å.
