Abstract
Complexes of Li, Na, Ba, and Er with 1,5-bis[2-(diphenylphosphinyl)phenoxy]-3-oxapentane (L) were synthesized and their IR spectra were examined. Some of the complexes were studied by thermogravimetric methods. The structures of the synthesized compounds were suggested on the basis of their spectra and previous X-ray studies. In Ba and Er complexes, L was found to be coordinated to the metal atom through the phosphoryl oxygen atoms, whereas in Li and Na complexes, both the phosphoryl and anisole oxygen atoms are involved in coordination. The structures of complexes was determined to depend on the nature of a metal and acidoligand and on the ratio of reagents used in the synthesis.
