Abstract
C-F…M+ interaction was clearly shown by using fluorinated macrocyclic cage compounds. The interaction was proved by complexation studies, spectroscopic measurements (1H, 19F, 13C NMR), and X-ray crystallographic analyses. By the complexation, specific spectroscopic changes were observed. Especially, Cs+ and Tl+ complexes showed F…M+ spin couplings. In the crystal structure, short F…M+ contacts were observed, and C-F bond distances are elongated by the complexation. The C-F unit acts as an efficient donor in the complexes, which was proved by estimating bond valences (C-F…M+, O.-M+, and N.-M+) of the cations by Brown's equation. The nature of the C-F…M+ interaction was proved to be a cation-dipole interaction, and coordination bond is weak in this case.
