Materials Data on Pb(NO3)2 by Materials Project

Pb(NO3)2 crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Pb2+ is bonded to twelve equivalent O2- atoms to form corner-sharing PbO12 cuboctahedra. There are six shorter (2.78 Å) and six longer (2.94 Å) Pb–O bond lengths. N5+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All N–O bond lengths are 1.27 Å. O2- is bonded in a single-bond geometry to two equivalent Pb2+ and one N5+ atom.
