Materials Data on Cs(FeP)2 by Materials Project
Cs(FeP)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cs1+ is bonded in a distorted body-centered cubic geometry to eight equivalent P3- atoms. All Cs–P bond lengths are 3.70 Å. Fe+2.50+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing FeP4 tetrahedra. All Fe–P bond lengths are 2.19 Å. P3- is bonded in a 4-coordinate geometry to four equivalent Cs1+ and four equivalent Fe+2.50+ atoms.
