Materials Data on Al(FeB)2 by Materials Project
AlFe2B2 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Fe is bonded in a 10-coordinate geometry to four equivalent Al and six equivalent B atoms. All Fe–Al bond lengths are 2.60 Å. There are four shorter (2.15 Å) and two longer (2.16 Å) Fe–B bond lengths. Al is bonded in a 2-coordinate geometry to eight equivalent Fe and two equivalent B atoms. Both Al–B bond lengths are 2.27 Å. B is bonded in a 9-coordinate geometry to six equivalent Fe, one Al, and two equivalent B atoms. Both B–B bond lengths are 1.75 Å.
