摘要

Two anion complexes of a tripodal tris(ferrocenylurea) receptor (L), (LH)·CF₃SO₃ (1) and (LH)·HSO₄ (2), were obtained from L and triflic acid or sulfuric acid, respectively. Crystal structural analyses show that the receptor in the two 1:1 (host/guest) complexes is protonated (on the bridgehead tertiary amine), and the CF ₃SO₃^- or HSO₄^- anion is located outside the tripodal cavity and anchored by the urea and CH groups of the receptor by hydrogen bonds. ¹H NMR spectroscopic studies confirmed the binding mode in solution.
