PrZnPO crystallizes in the trigonal R-3m space group. Pr(1) is bonded in a 4-coordinate geometry to three equivalent P(1) and four equivalent O(1) atoms. Zn(1) is bonded to four equivalent P(1) atoms to form a mixture of corner and edge-sharing ZnP4 tetrahedra. P(1) is bonded in a 7-coordinate geometry to three equivalent Pr(1) and four equivalent Zn(1) atoms. O(1) is bonded to four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing OPr4 tetrahedra.
PrZnPO crystallizes in the trigonal R-3m space group. Pr(1) is bonded in a 4-coordinate geometry to three equivalent P(1) and four equivalent O(1) atoms. All Pr(1)-P(1) bond lengths are 3.12 Å. All Pr(1)-O(1) bond lengths are 2.41 Å. Zn(1) is bonded to four equivalent P(1) atoms to form a mixture of corner and edge-sharing ZnP4 tetrahedra. There are three shorter (2.43 Å) and one longer (2.55 Å) Zn(1)-P(1) bond length. P(1) is bonded in a 7-coordinate geometry to three equivalent Pr(1) and four equivalent Zn(1) atoms. O(1) is bonded to four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing OPr4 tetrahedra.
