The material described by PrCuO2 crystallizes in the trigonal R-3m space group. Pr(1) is bonded to six equivalent O(1) atoms to form distorted edge-sharing PrO6 octahedra. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Pr(1) and one Cu(1) atom to form a mixture of edge and corner-sharing OPr3Cu tetrahedra. is represented by the CIF file [CIF]
