The syntheses, characterization and coordination chemistry of two new 1,10‐phenanthroline‐based ligands are presented here. Crystallographic studies have shown that both molecules display hydrogen‐bonding and π−π stacking interactions, generating interesting supramolecular assemblies in the solid state. The reactions of these ligands with [RuCl2(PPh3)3] have been performed and two new ruthenium‐amidato complexes have been prepared. In both cases, the presence of a pyridyl group in the ligand backbone favours the deprotonation of one of the carboxyamido moieties leading to a tridentate coordination mode of the ligands. The structural characterization of one of the ruthenium complexes is also reported. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
