The structure described by Fe2Pb3N4 crystallizes in the monoclinic C2/c space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing FeN4 tetrahedra. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. In the second Pb site, Pb(2) is bonded in a bent 120 degrees geometry to two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to two equivalent Fe(1), one Pb(1), and one Pb(2) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to two equivalent Fe(1) and two equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
