The effect of spacer chain length on ion binding to bidentate α,ω-diamines: Contrasting ordering for H+ and Li+ ion affinities

Abstract

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 α,ω-diamines.
