2D NMR Spectroscopic Evidence for Unprecedented Interactions of cis‐[Rh2(dap)(μ‐O2CCH3)2(η1‐O2CCH3)(CH3OH)](O2CCH3) with a DNA Oligonucleotide: Combination of Intercalative and Coordinative Binding

Abstract

Slip it in: The dual capability of intercalation and coordination binding of dirhodium complexes was observed in the reaction of the title complex with d(CTCTCAACTTCC). A major adduct with the 1,12-diazaperylene (dap) group intercalated between the A6 and A7 residues was produced. Additionally, the Rh atom that is not bound to the dap group forms a coordinative bond to the N7 site of A6.
