Abstract Band gap tuning of nanomaterials is a current field of interest in order to transform UV-light active catalysts into visible light driven catalysts. Tungsten-doped SnO2 (W@SnO2) nanospheres (NS) with dopant concentration ranging from 0 to 6 mol%, were prepared and characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectrometry (ICP-OES) and UV-Visible spectroscopy. The ...

Abstract In this work multiwall carbon nanotubes (MWCNTs) oxidized with UV-O3 are functionalized with triethylenetetramine (TETA) moiety. A new type of radiation-protective nanocomposite films has been fabricated by free radical polymerisation of methyl methacrylate (MMA) in the presence of the metal-supported, chemically functionalized and highly dispersed MWCNTs, while the long-chain amides, grafted on the MWCNTs surface provide anchorage site for deposits of Ag nanoparticles. The nanocomposit...

Abstract This article focus on the synthesis of three 5-coordinated Sn(IV) complexes based on carboxylate ligand: 4-((4-methoxy-2-nitrophenyl)amino)-4-oxobutanoic acid. The complexes were characterized in both solid state (FT-IR, single crystal XRD and micro elemental analysis) as well as in solution state (1H, 13C and 119Sn NMR) and their results demonstrate that the carboxylate moiety of the ligand is linked with Sn atom. A 5-coordinated trigonal bipyramidal structure was obtained from crystal...

Abstract Two azomethines: (E)-2-(((2-hydroxyethyl)imino)methyl)-6-methoxyphenol (1) and (E)-3-(((2-hydroxyethyl)imino)methyl)benzene-1,2-diol (2) were synthesized and characterized in solid state by FT-IR spectroscopy and single crystal X-ray crystallography, whereas in solution state by NMR (1H, 13C) and GC-MS. The titled compounds exist in a zwitter ionic form with a strong intramolecular N–H⋯O hydrogen bond between the NH+ and the phenolate O− as observed both in solution states as well as in...

Abstract In this study, Cd(II) complexes including three homoleptic and six heteroleptic Cd(II) carboxylates were synthesized in water at ambient conditions. Five different ligands (4-chlorophenylacetic acid, 3-chlorobenzoic acid, diphenyl acetic acid, 1,10-phenanthroline and 2,2-bipyridine) were used to synthesize the Cd(II) complexes and characterized by analytical techniques (SCXRD, 1H NMR, 13C NMR, FTIR, DRS and melting point). These complexes were investigated for anti-bacterial activity (a...

Abstract 2-Phenylbutyric acid based four organotin (IV) complexes were prepared with general formula R3SnL/R2SnL2, where R = methyl (1), butyl (2), octyl (3) and L = 2-phenylbutyrate. The 2-phenyl butyrate coordinates to the tin atom via carboxylate group as evidenced by FT-IR and 13C NMR data. Moreover, skew-trapezoidal bipyramidal geometry was observed for complex 3 by single crystal X-ray diffraction data. The prepared complexes were evaluated for antibacterial action against four plant patho...

Abstract New dimeric paddlewheel copper(II) mixed ligand complexes were synthesized having general formulae [(py)Cu(L)4Cu(py)] (1) , [(clpy)Cu(L*)4Cu(clpy)] (2) and [(py)Cu(L°)4Cu(py)] (3) where HL = 4-bromophenylacetic acid, HL* = phenyl acetic acid, HL° = 2-nitrophenylacetic acid, py = pyridine, clpy = 2-chloropyridine and characterized via FT-IR, powder and single crystal XRD, electrochemical solution studies and electron spin resonance spectroscopy. The resultant structures are dimeric paddl...
