Editing Lead styphnate (section)

==Structure==
Normal lead styphnate exists as α and β polymorphs, both being monoclinic crystals. The lead centres are seven-coordinate and are bridged via oxygen bridges. The water molecule is coordinated to the metal and is also hydrogen-bonded to the anion. Many of the Pb-O distances are short, indicating some degree of covalency. The styphnate ions lie in approximately parallel
planes linked by Pb atoms.<ref>{{cite journal|author=Pierce-Butler, M.A.|title=The structure of the lead salt of 2,4,6-trinitro-1,3-benzenediol monohydrate (alpha-polymorph)|journal=Acta Crystallogr.|year=1984|doi=10.1107/S0108270184003036|volume=40|pages=63–65}}</ref><ref>{{cite journal|author=Pierce-Butler, M.A.|title=Structures of the barium salt of 2,4,6-trinitro-1,3-benzenediol monohydrate and the isomorphous lead salt (beta-polymorph)|journal=Acta Crystallogr.|year=1982|doi=10.1107/S0567740882010966|volume=38|issue=12|pages=3100–3104}}</ref>
