title: Tris(1-ethyl-3-methylimidazolium) hexachlorolanthanate.
abstract: In the title complex, (C(6)H(11)N(2))(3)[LaCl(6)], centrosymmetric octahedral hexachlorolanthanate anions are located at the corners and face-centers of the monoclinic unit cell. The ring H atoms of the cations interact with the Cl atoms of the anions via hydrogen bonding, and bifurcation of the hydrogen bonding is observed. Cation-cation interactions via hydrogen bonding between the ring H atoms and pi-electrons of aromatic rings are also observed as in other imidazolium salts.
