NaCr2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Na(1) is bonded to four equivalent O(1) atoms to form NaO4 tetrahedra that share corners with twelve equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 62°. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Na(1)O4 tetrahedra and edges with six equivalent Cr(1)O6 octahedra. O(1) is bonded to one Na(1) and three equivalent Cr(1) atoms to form a mixture of edge and corner-sharing ONaCr3 tetrahedra.
