Collapsed Cu(II)-hydroxamate metallacrowns.
The tetranuclear compounds are the first examples of solely hydroxamate-based Cu(II) metallacrown complexes with a collapse of the metallamacrocyclic cavity.
Efficient stabilization of copper(III) in tetraaza pseudo-macrocyclic oxime-and-hydrazide ligands with adjustable cavity size.
Substitution of the amide donors in open-chain {2N(oxime), 2N(amide)} ligands by hydrazide donors gives new pseudo-macrocyclic copper complexes that show a significant decrease of the Cu(3+/2+) redox
Chelating dihydroxamic acids: study of metal speciation and co-ordination compounds with Ni2+ and Cu2+
Solution (potentiometric, absorption, EPR) as well as solid state studies (X-ray, EPR, magnetic susceptibility) have shown that the binding ability of oxalodihydroxamic acid (H2oxha) with two
Encapsulation of a guest sodium cation by iron(III) tris-(hydroxamate)s.
An unprecedented encapsulation of an exogenous sodium ion by iron(III) tris(hydroxamate)s was observed upon crystallization of an iron(III) complex with isonicotinylhydroxamic acid. The sodium cation
Synthesis and structure of [2 x 2] molecular grid copper(II) and nickel(II) complexes with a new polydentate oxime-containing Schiff base ligand.
P pH potentiometric, electrospray ionization mass spectrometric, and spectrophotometric studies of complex formation in H 2O/DMSO solution confirmed the preference for polynuclear complexes with 3d metal ions.
Iron chelating strategies in systemic metal overload, neurodegeneration and cancer.
It was shown, that desferrioxamine and deferasirox are antiproliferative agents active in several types of cancer and very potent compounds with possible use as anticancer drugs are thiosemicarbazones.
