In the title compound, (C12H9N)4[EuCl6]Cl, the EuIII atom has slightly distorted octa-hedral coordination. The longest Eu - Cl bond (Table 1) is to a Cl atom that serves as acceptor of a hydrogen bond from one of the four crystallographically independent singly-protonated 1,10-phenanthrolinium cations. The other three cations all form hydrogen bonds to the uncoordinated chloride anion, which is surrounded approximately in a trigonal plane by the three donors (Table 2). There is extensive π-stacking of the planar cations, with inter-planar distances in the range 3.3-3.7Å. © International Union of Crystallography 2007.
