Abstract
Complex formation between metal cations and macrocyclic ligands has been observed by fast atom bombardment (F.A.B) mass spectrometry of their aqueous glycerol and other solutions, the abundances of gas-phase ions at m/z values corresponding to metal cation–ligand complexes reflecting closely the calculated concentrations of these complexes in solution at normal temperatures; the results suggest that metal cation–ligand complex formation in solution for wide ranges of metal cations and many different types of macrocyclic ligands can be assessed rapidly and semi-quantitatively by the F.A.B. technique.Keywords
