Alkalli metal complexes with N-(4′-Benzo-15-Crown-5)-2-(amino-N-tosyl)-phenylaldimine

Complexes of Li, Na, and K with N-(4'-benzo-15-crown-5)-2-(amino-N-tosyl)-phenylaldimine (L) are synthesized and their IR spectra are studied with assignment of the basic vibration frequencies of the ligand and complexes. The conformation states of macrocycles in the title complexes are analyzed. The macrocycle conformation in complexes of L with the Li, Na, and K salts is not influenced by the nature of a metal or acido ligands. The structures of the synthesized compounds are suggested on the basis of the spectral and elemental analysis data.
