Tetrakis(1,10-phenanthrolinium) hexachloridoeuropate(III) chloride

W. Clegg and R. W. Harrington

Abstract: In the title compound, (C₁₂H₉N)₄[EuCl₆]Cl, the Eu^III atom has slightly distorted octahedral 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 -stacking of the planar cations, with interplanar distances in the range 3.3-3.7Å.
