Electrospray ionization mass spectrometric analysis of the Ag29 lipoate complex in solution. (A) Cluster can be detected intact thus confirming its composition and 3- charge state. The observed peak positions and isotopic patterns agree with those calculated (green trace) from the chemical formulas given, assuming all lipoic acid carboxyl groups are protonated (−CO2H). (B) Cluster can be induced to fragment by loss of lipoate ligands while keeping its silver count intact at 29.
