The Great COVID-19 Divergence: Managing a Sustainable and Equitable Recovery in the EU.

The COVID-19 pandemic has led to the biggest global recession since the Second World War. Forecasts show the European Union underperforming economically relative to the United States and China during 2019-2023. Southern European countries have been particularly strongly affected.

Synthesis, crystal structures and spectroscopy of meclofenamic acid and its metal complexes with manganese(II), copper(II), zinc(II) and cadmium(II). Antiproliferative and superoxide dismutase activity.

Some new complexes of meclofenamic acid (N-(2,6-dichloro-m-tolyl)anthranilic acid), Hmeclo (1), with potentially interesting biological activities are described. Complexes [Mn(meclo)(2)] (2), [Cu(meclo)(2)(H(2)O)(2)] (3), [Zn(meclo)(2)(H(2)O)(2)] (4) and [Cd(meclo)(2)(H(2)O)(2)] (5) were prepared and structurally characterized by means of vibrational, electronic and (1)H and (13)C NMR spectroscopies. The crystal structure of complexes [Cu(4)(meclo)(6)(OH)(2)(DMSO)(2)]2DMSO (3a) and [Cd(meclo)(2)(DMSO)(3)] (5a) have been determined by X-ray crystallography.

Diorganotin complexes of a thiosemicarbazone, synthesis: properties, x-ray crystal structure, and antiproliferative activity of diorganotin complexes.

The synthesis and spectral characterization of novel diorganotin complexes with 3-hydroxypyridine-2-carbaldehyde thiosemicarbazone, H(2)L(1), [SnMe(2)(L)] (2), [SnBu(2)(L)] (3), and [SnPh(2)(L)] (4) are reported. The single-crystal X-ray structure of complex [SnPh(2)(L)(DMSO)] (5) shows that the ligand is doubly deprotonated and is coordinated as tridentate ligand. The six coordination number is completed by two carbon atoms of phenyl groups.

Organotin Compound Derived from 3-Hydroxy-2-formylpyridine Semicarbazone: Synthesis, Crystal Structure, and Antiproliferative Activity.

The novel diphenyltin(IV) compound [Ph(2)(HyFoSc)Sn] (2), where H(2)HyFoSc (1) is 3-hydroxy-2-formylpyridine semicarbazone, was prepared and characterized by vibrational and NMR ((1)H, (13)C) spectroscopy. The structure of [Ph(2)(HyFoSc)Sn] was confirmed by single-crystal X-ray crystallography. The doubly deprotonated ligand is coordinated to the tin atom through the enolic-oxygen, the azomethine-nitrogen, and phenolic-oxygen, and so acts as an anionic tridentate ligand with the ONO donors.

Zinc(II) complexes of 2-acetyl pyridine 1-(4-fluorophenyl)-piperazinyl thiosemicarbazone: Synthesis, spectroscopic study and crystal structures - potential anticancer drugs.

2-Acetyl pyridine thiosemicarbazone containing an 1-(4-fluorophenyl)-piperazinyl ring incorporated at N(4)-position, HAcPipPheF (1) and the zinc(II) complexes [Zn(AcPipPheF)(2)] (2) and [Zn(OAc)(AcPipPheF)](2) (3) have been prepared and structurally characterized by means of vibrational and NMR ((1)H and (13)C) spectroscopy. The crystal structures of the compounds 1-3 have been determined by X-ray crystallography. The metal coordination geometry of [Zn(AcPipPheF)(2)] is described as distorted octahedral configuration in a trans-N-cis-N-cis-S configuration.
