The crystal structure described by BaNb2O6Cr crystallizes in the cubic Fm-3m space group. The structure consists of four 7440-47-3 atoms inside a BaNb2O6 framework. In the BaNb2O6 framework, Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra and faces with eight equivalent Nb(1)O6 octahedra. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Ba(1) and two equivalent Nb(1) atoms. is represented by the CIF card [CIF]
