The characterized by 1H NMR and IR spectroscopic techniques, while its structure determined single-crystal X-ray diffraction analysis. In title compound, each ion is coordinated three nitrogen atoms, as corresponding (amine NA, deprotonated amide...
The synthesis and characterization of novel hetrometallic complexes [{ cis ‐PtCl(NH 3 ) 2 ( μ ‐4,4′‐bipyridyl)ZnCl(terpy‐Cl)}](ClO 4 C1a ), trans ‐4,4′‐bipyridyl)ZnCl(terpy)}](ClO C2a ‐pyrazine)ZnCl(terpy‐Cl)}](ClO C3a C4a (where terpy‐Cl = 4′‐chloro‐2,2′:6′,2′′‐terpyridine) was done. Acid–base titrations were performed by UV–Vis spectrophotometric method to evaluate the p K a values corresponding aqua complexes. Interactions between important biomolecules, guanosine‐5′‐monophosphate...
A series of mono- and heteronuclear platinum(II) zinc(II) complexes with 4,4′,4″-tri-tert-butyl-2,2′:6′,2″-terpyridine ligand were synthesized characterized. The DNA protein binding properties [ZnCl2(terpytBu)] (C1), [{cis-PtCl(NH3)2(μ-pyrazine)ZnCl(terpytBu)}](ClO4)2 (C2), [{trans-PtCl(NH3)2(μ-pyrazine)ZnCl(terpytBu)}](ClO4)2 (C3), [{cis-PtCl(NH3)2(μ-4,4′-bipyridyl)ZnCl(terpytBu)}](CIO4)2 (C4) [{trans-PtCl(NH3)2(μ-4,4′-bipyridyl)ZnCl(terpytBu)}](CIO4)2 (C5) (where terpytBu =...
The negative environmental and social impacts of food waste accumulation can be mitigated by utilizing bio-refineries' approach where is revalorized into high-value products, such as prodigiosin (PG), using microbial bioprocesses. diverse biological activities PG position it a promising compound, but its high production cost promiscuous bioactivity hinder wide application. Metal ions modulate the electronic properties organic molecules, leading to novel mechanisms action increased target...
Three new silver(I) complexes [Ag(NO3)(tia)(H2O)]n (Ag1), [Ag(CF3SO3)(1,8-naph)]n (Ag2) and [Ag2(1,8-naph)2(H2O)1.2](PF6)2 (Ag3), where tia is thianthrene 1,8-naph 1,8-naphthyridine, were synthesized structurally characterized by different spectroscopic electrochemical methods their crystal structures determined single-crystal X-ray diffraction analysis. Their antimicrobial potential was evaluated against four bacterial three Candida species, the obtained results revealed that these showed...
The hexadentate 1,3-propanediamine-N,N,N',N'-tetraacetate (1,3-pdta4−) and (±)-1,3-pentanediamine-N,N,N',N'-tetraacetate (1,3-pndta4−) ligands were used for the synthesis of two new gallium(III) complexes, Na[Ga(1,3-pdta)]·3H2O (1) Ba[Ga(1,3-pndta)]2·3H2O (2). Complexes 1 2 characterized by IR NMR (1H 13C) spectroscopy single crystal X-ray diffraction analysis. obtained results have shown that both 1,3-pdta4− 1,3-pndta4− are coordinated to ion through nitrogen four carboxylate oxygen atoms....
The mechanism of substitution from tetrahedral [ZnCl2(en)] and square-pyramidal [ZnCl2(terpy)] complexes (where en = 1,2-diaminoethane or ethylenediamine terpy 2,2′:6′,2′′-terpyridine) by guanosine-5′-monophosphate (5′-GMP) have been investigated 1H NMR spectroscopy. reaction complex is faster than the [ZnCl2(en)], which was finished after 48 h. Information about structures final products in solution were obtained DFT calculations (B3LYP/6-31G(d)) experimental data acquired during course...
This study was undertaken to determine the impact of organic complex concentration on adsorption herbicide (acetochlor) at surface modified montmorillonite. In this work, natural montmorillonite from Bogovina (Boljevac municipality, Serbia) used for modification. Cation-exchange capacity determined using a methylene blue method (86 mmol/100 g clay). Montmorillonite has been first with NaCl and then hexadecyltrimethylammonium bromide (HDTMA-bromide) complex. Saturation cation exchange (CEC)...
The results of sorption acetochlor herbicide with different concentrations (1–15 µg/mL) in inorganic- and organic-modified bentonite are presented. Acetochlor both types was studied by attenuated total reflectance spectroscopy the mid-infrared region batch equilibrium method. Infrared suggest that interaction inorganic (or organic) takes place mechanism involving carbonyl stretching vibration phenyl ring molecule. increase concentration red shift corresponding band wavenumbers.

The results presented in this paper show an impact of the concentration aromatic organic cation on adsorption acetochlor surface organic-modified montmorillonite. Natural montmorillonite from Bogovina (Boljevac municipality, Serbia) was used for modification experiment. Cation exchange capacity (86 mmol 100 g−1 clay) determined using methylene blue method. In pretreatment, modified with NaCl. For purpose modification, three different concentrations phenyltrimethylammonium chloride (PTMA)...
In the present study, a zinc(II) complex with 4-ethynyl-2,2?-bipyridine (ebpy), [Zn(ebpy)Cl2], was synthesized and characterized by spectroscopic (1H-NMR, IR UV?Vis) methods molar conductivity measurement.
