Full range electrospray ionization mass spectrum (ESI MS) of the mixture of Ag25(DMBT)18 (I) and Au25(PET)18 (II) at molar ratio (I:II) of 0.3:1.0 measured within 2 min after mixing (a), zoomed in region of panel a in the range between m/z 5,270 and 7,340 showing a feature due to the dianionic adduct, (Ag25Au25(DMBT)18(PET)18)2− formed between I and II (b) and theoretical (blue) and experimental (red) isotope patterns of the adduct features (c). DMBT is 2,4-dimethylbenzenethiol and PET is 2-phenylethanethiol.
