Materials Data on PrPOsO by Materials Project
PrOsPO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr3+ is bonded in a 4-coordinate geometry to four equivalent P3- and four equivalent O2- atoms. All Pr–P bond lengths are 3.39 Å. All Pr–O bond lengths are 2.36 Å. Os2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing OsP4 tetrahedra. All Os–P bond lengths are 2.36 Å. P3- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Os2+ atoms. O2- is bonded to four equivalent Pr3+ atoms to form a mixture of edge and corner-sharing OPr4 tetrahedra.
