Pb3P crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pb is bonded in a 10-coordinate geometry to eight equivalent Pb and two equivalent P atoms. There are a spread of Pb–Pb bond distances ranging from 3.26–3.49 Å. Both Pb–P bond lengths are 3.35 Å. P is bonded in a 6-coordinate geometry to six equivalent Pb atoms.
