Novel 24-membered octanuclear manganese(III) metallacrown

Bulletin of the Chemical Society of Ethiopia, 2014
A novel octanuclear manganese metalladiazamacrocycle (1) was synthesized employing a new pentadentate ligand N-methacryl-5-methylsalicylhydrazide (H3mamshz) by supramolecular self assembly.

Synthesis and Structural Characterization of a New Tetranuclear Nickel(II) Sulfato Complex Containing the Anionic Form of Di‐2‐Pyridyl Ketone Oxime

International Journal of Inorganic Chemistry, Volume 2011, Issue 1, 2011., 2011
The preparation and crystal structure of a tetranuclear Ni(II) sulfato cluster containing the anion of di‐2‐pyridyl ketone oxime, (py)2CNO−, are reported. Treatment of NiSO4·6H2O with one equivalent of (py)2CNOH and one equivalent of NEt3 in MeOH leads to the compound [Ni4{(py)2CNO}4(SO4)2(MeOH)4] (1) in moderate yield.

Use of the 2‐Pyridinealdoxime/N,N′‐Donor Ligand Combination in Cobalt(III) Chemistry: Synthesis and Characterization of Two Cationic Mononuclear Cobalt(III) Complexes

Bioinorganic Chemistry and Applications, Volume 2010, Issue 1, 2010., 2010
The use of 2‐pyridinealdoxime (paoH)/N,N′‐donor ligand (L‐L) “blend” in cobalt chemistry has afforded two cationic mononuclear cobalt(III) complexes of the general type [Co(pao) 2(L‐L)] +, where L‐L = 1,10‐phenanthroline (phen) and 2,2′‐bipyridine (bpy). The CoCl2/paoH/L‐L (1 : 2 : 1) reaction system in MeOH gives complexes [CoIII(pao) 2(phen)]Cl·2H2O (

In Vitro Evaluation of Oxoplatin: An Oral Platinum(IV) Anticancer Agent

Metal-Based Drugs, Volume 2009, Issue 1, 2009., 2009
Platinum(IV) compounds like oxoplatin (cis, cis, trans‐diammine‐dichlorido‐dihydroxido‐platinum(IV)) show increased stability and therefore can be applied orally. In a panel of 38 human cancer cell lines this drug induced S‐phase arrest and cell death with IC50 values 2.5‐fold higher than cisplatin.

Fluorescence Sensors for Lithium Ions and Small Peptides

CHIMIA, 2010
Simple but powerful chemosensors were developed by taking advantage of self-assembly processes. First, we will describe a turn-on fluorescent sensor for the pharmacologically important lithium ion.

Electronic Effects in 12-Metallacrown-3 Complexes. A Theoretical and Experimental Study

, 2016
The Mulliken charges of the 12-metallacrown-3 complex [(C6H6)Ru(C5H3NO2)]3 were determined by a single point analysis at the HF level. For comparison, a Mulliken population analysis was carried out for the organic analogue 12-crown-3.

Luminescent Lanthanide Complexes with Fluorinated Heterocycles as Light‐Harvesting Antennae

European Journal of Inorganic Chemistry, Volume 28, Issue 14, May 23, 2025.
The luminescence of trivalent lanthanide (Tb, Eu, Sm, Dy) coordination compounds was optimized. The electronic properties of the light‐harvesting antenna were modulated by regioselective fluorination and trifluoromethylation. The effects of the coordination geometry of the metal ion and the linker connecting the carbostyril and the metal‐binding site ...

Interaction of Imidazole Containing Hydroxamic Acids with Fe(III): Hydroxamate Versus Imidazole Coordination of the Ligands

Bioinorganic Chemistry and Applications, Volume 2007, Issue 1, 2007., 2007
Solution equilibrium studies on Fe(III) complexes formed with imidazole‐4‐carbohydroxamic acid (Im‐4‐Cha), N‐Me‐imidazole‐4‐carbohydroxamic acid (N‐Me‐Im‐4‐Cha), imidazole‐4‐acetohydroxamic acid (Im‐4‐Aha), and histidinehydroxamic acid (Hisha) have been performed by using pH‐potentiometry, UV‐visible spectrophotometry, EPR, ESI‐MS, and 1H‐NMR methods ...

Metallacrown of Ce^IIICu^II₅: Synthesis, Structural Characterization and Insights for Nanoparticles

Magnetochemistry
The heterobimetallic 15-MC-5 metallacrown of formula [CeCu5(5mpzHA)5(NO3)(H2O)7]·2NO3·7H2O, designated MC-Ce, was synthesized using 5-methyl-2-pyrazinehydroxamic acid (5mpzHA) as a linker, reacting with CeIII and CuII salts under mild conditions.
