Materials Data on CeZnPO by Materials Project
CeZnPO crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ce3+ is bonded in a 4-coordinate geometry to three equivalent P3- and four equivalent O2- atoms. All Ce–P bond lengths are 3.08 Å. There are one shorter (2.36 Å) and three longer (2.38 Å) Ce–O bond lengths. Zn2+ is bonded to four equivalent P3- atoms to form a mixture of corner and edge-sharing ZnP4 tetrahedra. There are three shorter (2.41 Å) and one longer (2.55 Å) Zn–P bond lengths. P3- is bonded in a 7-coordinate geometry to three equivalent Ce3+ and four equivalent Zn2+ atoms. O2- is bonded to four equivalent Ce3+ atoms to form a mixture of corner and edge-sharing OCe4 tetrahedra.
