Materials Data on FeAs by Materials Project
FeAs is Modderite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Fe3+ is bonded to six equivalent As3- atoms to form a mixture of distorted corner, edge, and face-sharing FeAs6 octahedra. The corner-sharing octahedra tilt angles range from 44–56°. There are a spread of Fe–As bond distances ranging from 2.32–2.50 Å. As3- is bonded in a 6-coordinate geometry to six equivalent Fe3+ atoms.
