The effect of spacer chain length on ion binding to bidentate alpha,omega-diamines: contrasting ordering for H+ and Li+ ion affinities.
Electrospray ionisation mass spectrometry studies and quantum chemical calculations indicate that bidentate ligation of Li+ ion to the diamines leads to symmetric bridging and exhibits contrasting relative affinity orderings compared to that of proton for alpha,omega-diamines.
