Materials Data on PrZnPO by Materials Project
PrZnPO crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Pr3+ is bonded in a 4-coordinate geometry to three equivalent P3- and four equivalent O2- atoms. All Pr–P bond lengths are 3.12 Å. All Pr–O bond lengths are 2.41 Å. Zn2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing ZnP4 tetrahedra. There are three shorter (2.43 Å) and one longer (2.55 Å) Zn–P bond lengths. P3- is bonded in a 7-coordinate geometry to three equivalent Pr3+ and four equivalent Zn2+ atoms. O2- is bonded to four equivalent Pr3+ atoms to form a mixture of edge and corner-sharing OPr4 tetrahedra.
