Materials Data on PrCuO2 by Materials Project

PrCuO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Pr3+ is bonded to six equivalent O2- atoms to form distorted edge-sharing PrO6 octahedra. All Pr–O bond lengths are 2.43 Å. Cu1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.82 Å. O2- is bonded to three equivalent Pr3+ and one Cu1+ atom to form a mixture of edge and corner-sharing OPr3Cu tetrahedra.
