The X‐ray structure of trans ‐[RuCl 3 (dmtp) 2 (9‐MeAde)] shows that this compound is the first crystallographic example of a ruthenium(III) complex with an adenine derivative coordinated as a monodentate ligand through the exocyclic N 6 nitrogen; two intramolecular hydrogen bonds stabilise the coordination of the adenine, which is present as a neutral ligand in the rare tautomeric imine form with a unique short C6−N6 distance of 1.293(3) Å.
