Abstract
1. Based on a study of the13C and17O NMR spectra of four macrocyclic polyethers, a difference in the character and mechanism of coordination of the ether and anisole oxygen atoms of the macroring with calcium was found during complexing. 2. The13C-{1h} signals of the carbons in the macrocyclic ring in benzo-12-crown-4 and benzo-15-crown-5 were assigned. The differences in the conformational state of these compounds were established.
