Bioorganometallic chemistry: Part 15. A novel molecular recognition process of host, trans-[Cp*Rh(η1(N3)-1-methylcytosine)(μ-OH)]2(OTf)2, with l-aromatic amino acid guests: selective hydrogen bonding to the μ-OH groups and the 1-methylcytosine ligands

The 1H-NMR and computer docking experiments have elucidated a novel molecular recognition process of host, trans-[Cp*Rh(η1(N3)-1-methylcytosine)(μ-OH)]2(OTf)2 (1), with l-aromatic amino acids, which is predicated on a selective hydrogen bonding regime of the NH3+ of the amino acid to one of the Rhμ-OH groups, as well as to a CO group of one of the other 1-methycytosine ligands, while the COO− H-bonds to an NH2 of the other 1-methycytosine ligand.
