The material structure described by PrOF is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. Pr(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. O(1) is bonded to four equivalent Pr(1) atoms to form OPr4 tetrahedra that share corners with six equivalent O(1)Pr4 tetrahedra, corners with ten equivalent F(1)Pr4 tetrahedra, edges with three equivalent O(1)Pr4 tetrahedra, and edges with three equivalent F(1)Pr4 tetrahedra. F(1) is bonded to four equivalent Pr(1) atoms to form FPr4 tetrahedra that share corners with six equivalent F(1)Pr4 tetrahedra, corners with ten equivalent O(1)Pr4 tetrahedra, edges with three equivalent O(1)Pr4 tetrahedra, and edges with three equivalent F(1)Pr4 tetrahedra. is represented by the CIF file [CIF]
