摘要
The X-ray structure of the potential antitumour complex trans-[RuCl3(H2O) (admtp)(2)] ? H2O (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.
