Materials Data on SmFePO by Materials Project
SmFePO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm3+ is bonded in a 4-coordinate geometry to four equivalent P3- and four equivalent O2- atoms. All Sm–P bond lengths are 3.27 Å. All Sm–O bond lengths are 2.29 Å. Fe2+ is bonded to four equivalent P3- atoms to form a mixture of corner and edge-sharing FeP4 tetrahedra. All Fe–P bond lengths are 2.38 Å. P3- is bonded in a 4-coordinate geometry to four equivalent Sm3+ and four equivalent Fe2+ atoms. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra.
