Journal ArticleDOI
TL;DR: A copper(II) complex of the most potent of the chelators, salicylaldehyde benzoyl hydrazone (SBH), exhibits significantly greater inhibitory activity than does SBH itself, and it is possible that aroylhydrozones of this type and/or their metal complexes could prove to be useful therapeutic agents.

Journal ArticleDOI
TL;DR: YPO4, ScPO4 and LuPO4 crystallize in the tetragonal system conforming to space group model I41/amd (D194h, No. 141), Z = 4.

Journal ArticleDOI
Olivier Kahn1
TL;DR: In this article, the authors proposed a strategy for the synthesis of polynuclear complexes with expected magnetic properties, namely, when the overlap between the magnetic orbitals is zero, the antiferromagnetic contribution is also zero and the coupling is purely ferromagnetic.

Journal ArticleDOI
TL;DR: In this article, the formation of hexacoordinated iron(II) complexes with octahedrally surrounded by monodentate ligands was identified and characterized by elemental analyses, IR and ligand field spectra and magnetic susceptibility measurements.

126 citations


Journal ArticleDOI
TL;DR: These findings offer a realistic explanation for the in vivo removal of iron from enterobactin without necessitating its destruction.

Journal ArticleDOI
TL;DR: In this paper, the equilibria existing in the VO 2+ -oxalic acid and -malonic acid systems have been studied pH-metrically and the proton exchanges between the bulk water and the different paramagnetic species have been insvestigated by measuring the T 2 relaxation time of water protons at 298 K, I = 10 M NaClO 4

Journal ArticleDOI
TL;DR: In this paper, a non-symmetrical, tetradentate Schiff base has been obtained in a two-step process, in which one mole of ethylene diamine is reacted with one Mole of acetylacetone to afford a 1:1 condensation product, which is then reacted with Mole of either salicylaldehyde or 2-hydroxyacetophenone to yield nonsymmetric diimines.

Journal ArticleDOI
TL;DR: Gold(0) dissolves in a wide range of aqueous amino acid solutions exposed to dioxygen as mentioned in this paper, which can be identified by circular dichroism.

Journal ArticleDOI
TL;DR: Ferrocenylidene derivatives of benzoyl, p-chlorobenzoyl-, o-nitrobenzoyl and salicyloyl- and isonicotinoyl hydrazines have been synthesised by condensing acetylferrocene and/or formylfersene with the respective aroyl hydrazine.

Journal ArticleDOI
TL;DR: In this article, a new cationic, water soluble phosphine (2-diphenylphosphinoethyl)trimethylammonium iodide, Ph 2 PCH 2 CH 2 NMe + 3 I −, (amphos iodide) has been synthesized and characterized.


Journal ArticleDOI
TL;DR: The anthracycline containing antibiotic daunorubicin binds metal ions with stabilities similar to those of quinizarin (1,4-dihydroxyanthraquinone) as discussed by the authors.

Journal ArticleDOI
TL;DR: In this paper, four tin(IV) complexes of tridentate dithiocarbazate Schiff bases have been synthesized and characterized by their elemental analyses and UV, IR, 1H NMR, and Mossbauer spectroscopies and X-ray powder diffraction.

Journal ArticleDOI
TL;DR: In this article, the reduction of polypyridine-type complexes of Cr(III, Ru(II), and Os(II) in the presence of S2O82− ions is accompanied by light emission.

Journal ArticleDOI
TL;DR: In this paper, the structure of 3 was determined at −17°C from 7634 independent reflections obtained with a computer automated diffractometer with a = 25.9 A3 and ϱcalcd = 1.5 A3.



Journal ArticleDOI
TL;DR: The reaction of nicotinic acid (nic), chromic perchlorate hexahydrate, and sodium perchlorates in aqueous solution affords a Cr(III)-vitamin complex whose composition has been established to be Na[Cr3O(nicH)6(H 2O)3][ClO4]8·nicH·6H2O, based on analytical data and single-crystal X-ray analysis.

Journal ArticleDOI
TL;DR: Competition between Zn(II) (or Cu(II)) and Cd( II) for the strong sites indicates that there is a common strong binding site for Cu( II), Zn (II) andCd(II), with higher affinity for Cu-II and Zn-II than for C d(II).

Journal ArticleDOI
TL;DR: AuCl3(tht) as mentioned in this paper is a neutral complex that reacts with neutral ligands to give dichloro-2[(phenylazo)phenyl]gold(III), [Au(Az)Cl2] with neutral monodentate ligands.

Journal ArticleDOI
TL;DR: In this article, the acidity constants of the protonated buffers given in the title were measured at 25 °C in water, 50% aqueous dioxane or methanol, and in 75 or 90% dimethylsulfoxide (Dmso) with tetramethylammonium nitrate as background electrolyte.


Journal ArticleDOI
TL;DR: In this paper, the mechanistic aspects of reductive elimination reactions in systems involving binuclear complexes are discussed and a variety of mechanisms are identified, including mononuclear complexes, binuclear species, and a single metal atom site.

Journal ArticleDOI
TL;DR: In this paper, the interaction of the following nitrogen-sulphur donor ligands with copper has been investigated: 2-(3,3-dimethyl-2-thiabutyl)benzimidazole (L1), 2-methylthio-2-,quinoline (L2), 2ethylthioethylamine (L3), 2-(2-ethylthiosulfur)pyridine (L4), 2

Journal ArticleDOI
TL;DR: Single crystal X-ray diffraction studies of two such complexes, [FeCla(SBH)(CHsOH)] and [CuCl( SBH)]~H,O, are reported, which show an ability to penetrate cell membranes and disrupt the intracellular metabolism of essential metal ions.

Journal ArticleDOI
TL;DR: In this article, absorption spectra for a series of metalloporphyrin π-radical cations produced by chemical oxidation in CH2Cl2 were reported and a good correlation between the energies of the first spin-allowed transitions for the π radical cation and for the parent porphrin was found.
