===Hydrated copper(II) nitrate=== Five [[water of hydration|hydrates]] have been reported: the monohydrate ({{chem2|Cu(NO3)2*2H2O}}),<ref name=Troyanov/> the sesquihydrate ({{chem2|Cu(NO3)2*1.5H2O}}),<ref>{{cite journal |last1=Dornberger-Schiff |first1=K. |last2=Leciejewicz |first2=J. |year=1958 |title=Zur Struktur des Kupfernitrates Cu(NO<sub>3</sub>)<sub>2</sub><sup>.</sup>1.5H<sub>2</sub>O |journal=[[Acta Crystallogr]] |volume=11 |issue=11 |pages=825β826 |doi=10.1107/S0365110X58002322 |doi-access=}}</ref> the hemipentahydrate ({{chem2|Cu(NO3)2*2.5H2O}}),<ref>{{cite journal |last1=Morosin |first1=B. |year=1970 |title=The crystal structure of Cu(NO<sub>3</sub>)<sub>2</sub>.2.5H<sub>2</sub>O |journal=[[Acta Crystallographica Section B]] |volume=26 |issue=9 |pages=1203β1208 |doi=10.1107/S0567740870003898}}</ref> a trihydrate ({{chem2|Cu(NO3)2*3H2O}}),<ref>J. Garaj, ''Sbornik Prac. Chem.-Technol. Fak.

This non-effect was attributed to the strong [[hydrogen bonding]] that limits the elasticity of the Cu-O bonds but it is probably due to nickel being misidentified as copper in the refinement.
