Ba2ReNiO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Re(1)O6 octahedra, and faces with four equivalent Ni(1)O6 octahedra. Re(1) is bonded to six equivalent O(1) atoms to form ReO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Re(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Ba(1), one Re(1), and one Ni(1) atom to form a mixture of distorted edge, corner, and face-sharing OBa4ReNi octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
