TL;DR: In this paper, a critical review of conversion constants amongst various reference electrodes reported in the literature reveals that in most cases the comparisons of redox potential values are far from accurate, and therefore, caution should be exercised when one is comparing the redox properties of complexes measured in CH 3 CN solutions versus different reference electrodes.

TL;DR: In this article, the authors show that only ferrocenium species are able to inhibit the growth of Ehrlich ascites tumor cells in vivo and propose that the cytotoxic activity of ferrocium salts is not based on their direct linking to DNA, but on their ability to generate oxygen active species which induce oxidative DNA damage.

TL;DR: In this paper, the magnetic properties of dinuclear copper(II) complexes are investigated as a function of temperature and the magnitude and nature of magnetic coupling through these extended bridges are analyzed and discussed in the light of available structural data.

TL;DR: In this paper, the authors investigated the complex formation of VO(IV) with the bidentate chelating ligands oxalic and malonic acids, of a dicarboxylic nature, and maltol and kojic acid of the hydroxy-4-pyrone type.

TL;DR: The amino acids complexes of [Pt(phen)(AA)]NO3·xH2O and [Pd(phen)Cl2] have been prepared by the interaction of palladium and platinum complexes with salts of amino acids in methanol and characterized by 1H NMR and IR spectroscopy as mentioned in this paper.

TL;DR: In this paper, the first Pb-citrate species was characterized analytically and spectroscopically (FT-IR) using X-ray crystallographic studies and showed the novel compound to be [Pb(C6H6O7)]n·nH2O.

TL;DR: In this paper, the electronic structure and the assignment of the bands in the electronic spectra of a series of nitrosyl-metal complexes [Ru(NH3)4(L)NO]n+, where L=NH3, H2O, pyrazine and pyridine (n = 3), Cl− and OH− (n=2).

TL;DR: In this paper, a structural evaluation was performed by IR and NMR spectroscopy and revealed a change of the linear acetylene core to a structure comparable to Z -olefins after coordination to the cobalt centers.

TL;DR: In this article, the EPR spectrum of the 2,2′-bipyridine (bpy) has been revisited by use of EPR and electronic absorption spectroscopies.

TL;DR: The entry and exit of Fe(II) ions in ferritin are endpoints in the process which concentrates iron as a solid (hydrated ferric oxide) to be used by living cells, suggesting a regulation-sensitive biological signal for iron exit.
