“…This work amplifies and extends brief earlier reports of the preparation of tris-maltolate [21] and tris-1,2-dimethyl-3-hydroxy-4-pyridinonate [22] complexes of ruthenium(III)-the latter having the unexpected formulation Ru(dmpp) 3 Cl. Our investigation also complements studies on the ruthenium(II) and ruthenium(III) pair of complexes [Ru(malt)Cl 2 (PPh 3 ) 2 ] x [23], and on several arene-ruthenium(II) complexes containing ligands of these types [24,25], one of which features in a pH-triggered assembly-disassembly process [26].…”

“…In addition, the nitrogen-containing heterocycle can be further functionalized. Severin and co-workers exploited the tendency to form coordination compounds and were the first to synthesize Ru II (arene) complexes with 4-pyridonato ligands [154] yielding triangular supramolecular metallocycles [155]. A similar self-assembly was observed for 2-pyridones featuring the structural motif of 12-crown-3 with selectivity for lithium ions (Fig.…”

“…[38] Ligands 1 a-h were converted with bis[dichlorido(h 6 -p-cyA C H T U N G T R E N N U N G mene)ruthenium(II)] under alkaline conditions into the corresponding Ru II complexes 2 a-h in good yields (61-85 %) (Scheme 1). [39] The reaction was performed with a slight excess of ligand to facilitate the purification step.…”

“…Similar behavior was also observed in the 13 C NMR spectra, in accord with related Ru II -arene complexes. [39] In the 1 H NMR spectrum of 2 e in CDCl 3 , two doublets with a coupling constant of 17 Hz were observed, which were assigned to the protons of the CH 2 group (see the Supporting Information). This geminal splitting can be explained by the formation of an intramolecular hydrogen bond between the hydroxymethyl moiety and the coordinated O3 atom.…”
