Crown-Ether Coordination Compounds of Europium and 24-Crown-8.

ABSTRACT: Crown-ether coordination compounds of europium(II/III) and the crown ether (C₂H₄O)₈ (24-crown-8, 24c8) are prepared, aiming at novel compounds, structures, and coordination modes as well as potential luminescence properties. By reacting EuCl₂, EuI₂, or EuCl₃ with 24c8 or its derivatives in ionic liquids, the novel compounds [Bu₃MeN]₂[Eu(II)(NTf₂)₄] (1), [BMIm]₆[Eu₃I₁₂] (2), [EuCl₂(dibenzo-18c6)] (3), [EuI₂(dibenzo-24c8)] (4), [(Eu(III)Cl₃)₂(C₁₄H₃₀O₈)](24c8) (5), and [Eu(III)Cl(24c8)]I₂ (6) are obtained (BMIm: 1-butyl-3-me
