Materials Data on PrCu3(RuO3)4 by Materials Project
PrCu3(RuO3)4 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Pr3+ is bonded to twelve equivalent O2- atoms to form PrO12 cuboctahedra that share faces with eight equivalent RuO6 octahedra. All Pr–O bond lengths are 2.64 Å. Ru+4.50+ is bonded to six equivalent O2- atoms to form RuO6 octahedra that share corners with six equivalent RuO6 octahedra and faces with two equivalent PrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 42°. All Ru–O bond lengths are 2.02 Å. Cu1+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.96 Å. O2- is bonded in a 4-coordinate geometry to one Pr3+, two equivalent Ru+4.50+, and one Cu1+ atom.
