Abstract
Hydrogen bonding stabilizes the binding of Pt ammine cations to oligonucleotides. Model calculations explore the energetics of the binding of the ammine to G (O6) in PtA3G (A = ammine, G = guanine) and the intermolecular binding of a carbonyl oxygen to the aremine in a complex of PtA4 and formaldehyde as a model of binding to carbonyl sites in thymine. Hydrogen-bondig interaction to the G(O6) site is weak but permits the close approach of the O6 and H atoms. Intermolecular hydrogen bonding is strong, as expected for an optimal ionic hydrogen bond.
