The structure described by K2PbCu(NO2)6 crystallizes in the cubic F23 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 edge-sharing KO12 cuboctahedra. In the second K site, K(2) is bonded to twelve equivalent O(1) atoms to form edge-sharing KO12 cuboctahedra. Cu(1) is bonded in an octahedral geometry to six equivalent N(1) atoms. Pb(1) is bonded in a distorted q6 geometry to twelve equivalent O(1) atoms. N(1) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to one K(1), one K(2), one Pb(1), and one N(1) atom. is represented by the CIF card [CIF]
