Its [[space group]] is Pa3<sub>Z=4</sub> ([[Bravais lattice]] notation), with each side of the cube with length 784&nbsp;[[picometre]]s.

The black dots represent the lead atoms, the white dots the nitrate groups 27&nbsp;picometres above the plane of the lead atoms, and the blue dots the nitrate groups the same distance below this plane. In this configuration, every lead atom is [[chemical bond|bonded]] to twelve oxygen atoms ([[bond length]]: 281&nbsp;pm). All N–O bond lengths are identical, at 127&nbsp;picometres.<ref>{{cite journal|url=https://scripts.iucr.org/cgi-bin/paper?a25608|title=Cấu trúc của chì nitrat|journal=[[Acta Crystallographica Section C]]|date=15 February 1986|volume=42 |issue=2 |pages=133–135 |doi=10.1107/S0108270186097032 |archive-url=|archive-date=|url-status=|accessdate =15 July 2019 |last1=Nowotny |first1=H. |last2=Heger |first2=G. |url-access=subscription }}</ref>

Research interest in the crystal structure of lead(II) nitrate was partly based on the possibility of free internal rotation of the nitrate groups within the crystal lattice at elevated temperatures, but this did not materialise.<ref name="nowotny"/>
