Ba2Ni(NO2)6 crystallizes in the cubic Fm-3m space group. Ba(1) is bonded in a 12-coordinate geometry to twelve equivalent O(1) atoms. Ni(1) is bonded in an octahedral geometry to six equivalent N(1) atoms. N(1) is bonded to one Ni(1) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing NNiO4 square pyramids. O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent N(1) atoms.
