Four mono- (1–4) and four binuclear Ru(II) arene (5–8) complexes have been isolated from the reaction of [Ru(η6-benzene)Cl(μ-Cl)]2 or [Ru(η6-toluene)Cl(μ-Cl)]2 with 2-pyridinecarboxylic acid and 6-fluoro-2-pyridinecarboxylic acid. Their structural characterization included IR and NMR spectroscopy and MS spectrometry. The cytotoxic potential of the compounds has been tested by MTT assay in seven human

Starting with a coordination polymer, [Cu(L)]2}n (1 where H2L = salicylidene-2-aminophenol), we have explored the ability of polypyridyl ligands (P) to bridge the monomer complex to form nine [Cu(L)]2(P)} complexes. The identity and solution stability of the [Cu(L)] units has been investigated through a novel combined UV–vis/EPR experiment and it has been found to be a stable supramolecular building

An exceptionally efficient ruthenium-based catalyst for olefin oxidation has been designed by exploiting N,N'-bis(pyridylidene)oxalamide (bisPYA) as a donor-flexible ligand. The dynamic donorability of the bisPYA ligand, imparted by variable zwitterionic and neutral resonance structure contributions, paired with the redox activity of ruthenium provided catalytic activity for Lemieux-Johnson-type oxidative
naphthazarine or metallaligand. Some of as‐synthesized BRs display high stability and are formed in high yields in solution. The reason is related to the length ratio of the long‐arm linker and short‐arm linker, where smaller aspect ratios of the metallarectangles promote improved stability and yields of the BRs in solution. Increasing the width of the metallaligand or pyridyl ligand hinders the formation of BRs

effective removal of toxic and carcinogenic PbII ions from aqueous solutions, a made-for-purpose functional group (N1 ,N2 -di(pyridine-4-yl)oxalamide) was rationally designed and incorporated into the cavities of a Zn metal-organicframework (MOF), namely, TMU-56. Large enough pore size along with high densities of strong metal chelating sites lead not only to the highest uptake capacity for PbII ions, but
