Novel rhodium, iridium, and ruthenium half-sandwichcomplexes containing (N,N)-bound picolinamide ligands have been prepared for use as anticancer agents. The complexes show promising cytotoxicities, with the presence, position, and number of halides having a significant effect on the corresponding IC50 values. One ruthenium complex was found to be more cytotoxic than cisplatin on HT-29 and MCF-7 cells

Addition of metal salts to a diiridium macrocyclic complex leads to the spontaneous formation of supramolecular particles that react preferentially with small substrates and can tolerate glutathione additives.

Direct N,N-dialkylation of acylhydrazide catalyzed by a series of amidato iridium complexes bearing an electron-donating group in the ligand using methanol or ethanol as the alkyl reagent under weak base conditions (10 mol % KHCO3) is described. A wide range of acylhydrazidederivatives are converted to the corresponding N,N-dialkylated products in excellent yields (38 examples, yields of ≤96%).
