Materials Data on Eu(FeAs)2 by Materials Project
EuFe2As2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu2+ is bonded in a body-centered cubic geometry to eight equivalent As3- atoms. All Eu–As bond lengths are 3.19 Å. Fe2+ is bonded to four equivalent As3- atoms to form a mixture of corner and edge-sharing FeAs4 tetrahedra. All Fe–As bond lengths are 2.31 Å. As3- is bonded in a 4-coordinate geometry to four equivalent Eu2+ and four equivalent Fe2+ atoms.
