Europium(III) nitrate is an inorganic compound with the formula Eu(NO3)3·x(H2O). The hexahydrate is a common salt. It forms colorless hygroscopic crystals.
The salt is usually obtained by dissolving europium(III) oxide (Eu2O3) in nitric acid produces europium(III) nitrate. [2]
Like all trinitrates of the lanthanides, dilute (<0.01 M) solutions of consists of the aquo complex [Eu(H2O)x]3+ where x = 8 or 9. At higher concentrations, the binding of nitrate to Eu is observed. [3]
Europium(III) nitrate reacts with anions and other Lewis bases to form complexes. For example, with 1,3,5-trimesic acid, europium metal-organic framework, a coordination polymer, under hydrothermal conditions. [4]
