Co2Pb3N4 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted trigonal pyramidal geometry to two equivalent N(1) and two equivalent N(2) atoms. In the second Co site, Co(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. In the second Pb site, Pb(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Co(1), one Co(2), one Pb(2), and two equivalent Pb(1) atoms to form a mixture of distorted edge and corner-sharing NCo2Pb3 trigonal bipyramids. In the second N site, N(2) is bonded in a distorted L-shaped geometry to one Co(1), one Co(2), one Pb(1), and one Pb(2) atom.
