K2NaCo(NO2)6 crystallizes in the cubic Fm-3 space group. K(1) is bonded to twelve equivalent O(1) atoms to form KO12 cuboctahedra that share edges with six equivalent K(1)O12 cuboctahedra and faces with four equivalent Na(1)O12 cuboctahedra. Na(1) is bonded to twelve equivalent O(1) atoms to form NaO12 cuboctahedra that share faces with eight equivalent K(1)O12 cuboctahedra. Co(1) is bonded in an octahedral geometry to six equivalent N(1) atoms. N(1) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to two equivalent K(1), one Na(1), and one N(1) atom.
