The X‐ray structure of the potential antitumour complex trans ‐[RuCl 3 (H 2 O)(admtp) 2 ] · H 2 O (admtp = 2‐amino‐5,7‐dimethyl[1,2,4]triazolo[1,5‐ a ]pyrimidine) shows unique and very interesting intramolecular hydrogen‐bonding properties with the non‐bridgehead pyrimidinic nitrogen atom of admtp acting as hydrogen acceptor and the amino group acting as hydrogen donor.
