Abstract

1, 17-bis-(Diphenylphosphinyl-3, 6, 9, 12, 15-pentaoxaheptadecane in MeCN forms complexes of 1∶1 and 1∶2 composition (M∶L) with alkali and alkaline-earth metal salts, complexes of 1∶1 and 2∶1 composition were found for Li salts. The BaL2+ complex is the most stable complex, and the complexes NH4L+ and CaL2+ are the least stable. The selectivity for Li is significantly higher for the podand studied than for crown ethers.
