Materials Data on NaCrO3 by Materials Project

NaCrO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Na1+ is bonded to twelve equivalent O2- atoms to form NaO12 cuboctahedra that share corners with twelve equivalent NaO12 cuboctahedra, faces with six equivalent NaO12 cuboctahedra, and faces with eight equivalent CrO6 octahedra. All Na–O bond lengths are 2.65 Å. Cr5+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent CrO6 octahedra and faces with eight equivalent NaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cr–O bond lengths are 1.87 Å. O2- is bonded in a distorted linear geometry to four equivalent Na1+ and two equivalent Cr5+ atoms.
