Abstract (PDF)
Graphical Abstract: A new synthetic extractive protocol for the synthesis of Cu(II) and Co(III) complexes of bis(2,2/-methylylidenephenol)diaminoethane (H2BMPDE) in a single simple step was performed. The obtained data indicated the formation of complexes with 1:1 molar ratio of metal:ligand, of distorted square planar and distorted octahedral geometries. In vitro antibacterial screening revealed that the complexes were active against clinically important gram-negative bacteria (Escherichia coli, pseudomonas, and gram-positive bacterium (Staphylococcus aureus). The synthesis of the complexes was optimized to make it more suitable and efficient for industrial scale production.

Abstract (PDF)
Graphical Abstract: Two crystalline compounds of germanium(IV) with malic acid (HMal) and 1,10ʹ-phenanthroline (phen) - [Ge(HMal)2(phen)]•pheh•2H2O (I) and [CuCl(phen)2][Ge(OH)(HMal)2] (II) were synthesized for the first time and characterized by elemental analysis, IR-spectroscopy and thermogravimetric analysis. There was elucidated from single-crystal X-ray diffraction that two different forms of Germanium are implemented: Ge4+ (I) and hydrolyzed GeOH3+ (II) to form distorted octahedron and pyramid respectively.

Abstract (PDF)
Graphical Abstract:
 The novel N-(methylene-2-pyridine)-N,N-bis(diethoxyphosphorylmethyl)amine ligand (L) was obtained through a double Kabachnik-Fields reaction, starting from 2-aminomethyl pyridine (2-picolylamine). Based on the L ligand, a new palladium(II) coordination compound [Pd(L)2Cl2] has been synthetized and comprehensively characterized by spectroscopic methods (1H NMR, UV-Vis), ESI mass spectrometry and X-ray crystallography.

Graphical Abstract: The crystalline compounds (Hbipy)2[Ge(HCitr)2]•2H2O (1)  and [CuCl(bipy)2]2[Ge(HCitr)2]•8H2O (2) (where H4Citr is citric acid, bipy is 2,2ʹ-bipyridine) were obtained for the first time and their structures were determined by the single-crystal X-ray diffraction method. The two compounds were characterized by IR spectroscopy, thermogravimetric (TGA) and elemental analyses. In both compounds complex bic(citrato)germanate anion is formed, protonated 2,2'-bipyridine molecule and [Cu(bipy)2Cl]+ complex are cations in 1 and 2, respectively.
