The characterized by elemental analysis, various spectroscopic techniques, single-crystal X-ray...
The synthesis and characterization of one oxidoethoxidovanadium(V) [VVO(L1)(OEt)] (1) two nonoxidovanadium(IV) complexes, [VIV(L2–3)2] (2 3), with aroylhydrazone ligands incorporating naphthalene moieties, are reported. synthesized oxido nonoxido vanadium complexes characterized by various physicochemical techniques, their molecular structures solved single crystal X-ray diffraction (SC-XRD). This revealed that in 1 the geometry around atom corresponds to a distorted square pyramid, O4N...
Five new anionic aqueous dioxidovanadium(V) complexes, [{VO2L1,2}A(H2O)n]α (1-5), with the aroylhydrazone ligands pyridine-4-carboxylic acid (3-ethoxy-2-hydroxybenzylidene)hydrazide (H2L1) and furan-2-carboxylic (H2L2) incorporating different alkali metals (A = Na+, K+, Cs+) as countercation were synthesized characterized by various physicochemical techniques. The solution-phase stabilities of 1-5 determined time-dependent NMR UV-vis, also octanol/water partition coefficients obtained...

The transport and cytotoxicity of molybdenum-based drugs have been explained with the concept chemical transformation, a very important idea in inorganic medicinal chemistry that is often overlooked interpretation biological activity metal-containing systems. Two monomeric, [MoO2(L1)(MeOH)] (1) [MoO2(L2)(EtOH)] (2), two mixed-ligand dimeric MoVIO2 species, [{MoO2(L1-2)}2(μ-4,4'-bipy)] (3-4), were synthesized characterized. structures solid complexes solved through SC-XRD, while their...
A series of mononuclear non-oxido vanadium(IV) complexes, [VIV(L1-4)2] (1-4), featuring tridentate bi-negative ONS chelating S-alkyl/aryl-substituted dithiocarbazate ligands H2L1-4, are reported. All the synthesized VIV compounds characterized by elemental analysis, spectroscopy (IR, UV-vis, and EPR), ESI-MS, as well electrochemical techniques (cyclic voltammetry). Single-crystal X-ray diffraction studies 1-3 reveal that complexes show distorted octahedral (1 2) or trigonal prismatic (3)...

Developing new anticancer agents can be useful, with the ability to diagnose and treat cancer worldwide. Previously, we focused on examining effects of nonoxidovanadium(IV) complexes insulin mimetic cytotoxicity activity. In this study, in addition cytotoxic activity, evaluated their bioimaging properties. This study investigates synthesis four stable nonoxido V
The reaction of 2-{2-(benzo[1,3]dioxol-5-yl)- diazo}-4-methylphenol (HL) with [Ru(PPh3)3Cl2] in ethanol resulted the carbonylated ruthenium complex [RuL(PPh3)2(CO)] (1), wherein metal-assisted decarbonylation via situ dehydrogenation is observed. When was performed acetonitrile, however, [RuL(PPh3)2(CH3CN)] (2) obtained as main product, probably by trapping a common intermediate through coordination CH3CN to Ru(II) center. analogous HL [Ir(PPh3)3Cl] did not result and instead gave...
