- •
All of A2M+ and G2M+ cations are planar structures in nucleobase-M+-nucleobase style, containing a nearly linear N–M+–N bond.
- •
The dissociation channels depend on the types of nucleobases and metal ions.
- •
The loss of one nucleobase (adenine or guanine) molecule are the predominant channels for M = Cu and Ag.
- •
The loss of AAu or GAu are the major channels for M = Au.
