K2CoPb(NO2)6 crystallizes in the orthorhombic Fmmm space group. K(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form KO12 cuboctahedra that share edges with six equivalent K(1)O12 cuboctahedra and faces with four equivalent Pb(1)O12 cuboctahedra. Co(1) is bonded in an octahedral geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. Pb(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form PbO12 cuboctahedra that share faces with eight equivalent K(1)O12 cuboctahedra. There are five inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(3) atoms. In the second N site, N(1) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(3) atoms. In the third N site, N(2) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(1) atoms. In the fourth N site, N(3) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(2) atoms. In the fifth N site, N(2) is bonded in a trigonal planar geometry to one Co(1) and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent K(1), one Pb(1), and one N(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent K(1), one Pb(1), and one N(3) atom. In the third O site, O(3) is bonded in a single-bond geometry to two equivalent K(1), one Pb(1), and one N(1) atom.
