Beryllium nitrate is an inorganic compound with the chemical formula Be(NO3)2. It forms a tetrahydrate with the formula [Be(H2O)4](NO3)2.The anhydrous compound, as for many beryllium compounds, is highly covalent. Little of its chemistry is known. Both the anhydrous form and the tetrahydrate are colourless solids that are soluble in water. The anhydrous form produces brown fumes in water, and produces nitrate and nitrite ions when hydrolyzed in sodium hydroxide solution.{{cite book |doi=10.1016/S0065-2792(08)60225-3|title=Anhydrous Metal Nitrates|series=Advances in Inorganic Chemistry and Radiochemistry|year=1964|last1=Addison|first1=C.C.|last2=Logan|first2=N.|volume=6|pages=71–142|isbn=9780120236060}}
Synthesis and reactions
The straw-colored adduct Be(NO3)2(N2O4) forms upon treatment of beryllium chloride with dinitrogen tetroxide in ethyl acetate:
:BeCl2 + 3{{nbsp}}N2O4 → Be(NO3)2(N2O4) + 2{{nbsp}}NOCl
Upon heating, this adduct loses N2O4 and produces colorless Be(NO3)2. Further heating of Be(NO3)2 induces conversion to basic beryllium nitrate (Be4O(NO3)6).{{Greenwood&Earnshaw2nd|page=122}}
Unlike the basic acetate, with its six lipophilic methyl groups, the basic nitrate is insoluble in most solvents.
The tetrahydrate is produced from the reaction of beryllium oxide or beryllium hydroxide with dilute nitric acid, followed by evaporation of the solution. The heating of the tetrahydrate does not yield the anhydrous form; instead it decomposes at 100 °C to beryllium hydroxide.{{cite book | title=Kirk-Othmer Encyclopedia of Chemical Technology | publisher=Wiley | date=2001-01-26 | isbn=978-0-471-48494-3 | doi=10.1002/0471238961.0205182519201514.a02.pub3 | url=https://onlinelibrary.wiley.com/doi/book/10.1002/0471238961 | ref={{sfnref|Wiley|2001}} | access-date=2025-05-21}}
Structure
File:Be4O(NO3)6 ICD Code59272.png
Basic beryllium nitrate adopts a structure akin to that of basic beryllium acetate.
The tetrahydrate consists of isolated [Be(H2O)4]2+ tetrahederons and nitrate anions. The structure of the anhydrous form has not been elucidated yet.{{cite journal | last=Divjakovič | first=V. | last2=Edenharter | first2=A. | last3=Nowacki | first3=W. | last4=Ribár | first4=B. | title=Die Kristallstruktur von Tetraaquo-Berylliumnitrat, Be(OH 2 ) 4 (NO 3 ) 2 | journal=Zeitschrift für Kristallographie - Crystalline Materials | volume=144 | issue=1-6 | date=1976-12-01 | issn=2196-7105 | doi=10.1524/zkri.1976.144.16.314 | pages=314–322 | url=https://www.degruyter.com/document/doi/10.1524/zkri.1976.144.16.314/html | access-date=2025-05-21}}{{cite journal | last=Scheibe | first=Benjamin | last2=Buchner | first2=Magnus R. | title=Carboxylic Acid Ester Adducts of Beryllium Chloride and Their Role in the Synthesis of Beryllium Nitrates | journal=European Journal of Inorganic Chemistry | volume=2018 | issue=20-21 | date=2018-06-07 | issn=1434-1948 | doi=10.1002/ejic.201800177 | pages=2300–2308 | url=https://chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/ejic.201800177 | access-date=2025-05-21}}
