The crystal structure described by In2Pb3N4 crystallizes in the monoclinic C2/c space group. In(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing InN4 trigonal pyramids. 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 water-like geometry to two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to two equivalent In(1) and two equivalent Pb(1) atoms. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent In(1), one Pb(1), and one Pb(2) atom. is represented by the CIF card [CIF]
