Materials Data on Ba(FeP)2 by Materials Project
BaFe2P2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a body-centered cubic geometry to eight equivalent P3- atoms. All Ba–P bond lengths are 3.36 Å. Fe2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing FeP4 tetrahedra. All Fe–P bond lengths are 2.21 Å. P3- is bonded in a 4-coordinate geometry to four equivalent Ba2+ and four equivalent Fe2+ atoms.
