Motorlet, 158 01 Prague 5-Jinonice


The hydration numbers of the complexes ML+ formed by some univalent cations (M+ = Li+, Na+, NH4+, K+, Rb+ and Cs+) and polyethylene glycol ligands (L = PEG 200, PEG 300 and PEG 400) in nitrobenzene saturated with water were determined. The highest differences between the hydration numbers of the cations M+ and the complexes ML+ were found in the systems with the Na+ cation.
