Materials Data on NaCu3(RuO3)4 by Materials Project
NaCu3Ru4O12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Na1+ is bonded to twelve equivalent O2- atoms to form NaO12 cuboctahedra that share faces with eight equivalent RuO6 octahedra. All Na–O bond lengths are 2.66 Å. Ru5+ is bonded to six equivalent O2- atoms to form RuO6 octahedra that share corners with six equivalent RuO6 octahedra and faces with two equivalent NaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 42°. All Ru–O bond lengths are 2.00 Å. Cu1+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.92 Å. O2- is bonded in a 3-coordinate geometry to one Na1+, two equivalent Ru5+, and one Cu1+ atom.
