K3Co(NO2)6 crystallizes in the cubic Fm-3 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to twelve equivalent O(1) atoms to form a mixture of face and edge-sharing KO12 cuboctahedra. In the second K site, K(2) is bonded to twelve equivalent O(1) atoms to form face-sharing KO12 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 single-bond geometry to one K(2), two equivalent K(1), and one N(1) atom.

In the first K site, K(1) is bonded to twelve equivalent O(1) atoms to form a mixture of face and edge-sharing KO12 cuboctahedra. All K(1)-O(1) bond lengths are 3.11 Å. In the second K site, K(2) is bonded to twelve equivalent O(1) atoms to form face-sharing KO12 cuboctahedra. All K(2)-O(1) bond lengths are 2.95 Å. Co(1) is bonded in an octahedral geometry to six equivalent N(1) atoms. All Co(1)-N(1) bond lengths are 1.97 Å. N(1) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(1) atoms. Both N(1)-O(1) bond lengths are 1.25 Å. O(1) is bonded in a single-bond geometry to one K(2), two equivalent K(1), and one N(1) atom.
