The crystal structure of the title compound, (C6H11N2)3
[EuBr6], consists of 1-ethyl-3-methylimidazolium cations and
centrosymmetric octahedral hexabromidoeuropate anions.
The [EuBr6]3- anions are located at the corners and facecentres of the monoclinic unit cell. Characteristic hydrogen bonding interactions can be observed between the bromide anions and the acidic H atoms of the imidazolium cations.
