Materials Data on Pb3N4 by Materials Project
Pb3N4 is beta Polonium structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Pb3N4 clusters. Pb4+ is bonded in a 2-coordinate geometry to two equivalent N3- atoms. Both Pb–N bond lengths are 2.43 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a T-shaped geometry to two equivalent Pb4+ and one N3- atom. The N–N bond length is 1.34 Å. In the second N3- site, N3- is bonded in a trigonal planar geometry to three equivalent N3- atoms.
