Synthesis, Characterization, Structural Description, Micellization Behavior, DNA Binding Study and Antioxidant Activity of 4, 5 and 6‐Coordinated Copper(II) and Zinc(II) Complexes

Abstract

Four mononuclear copper(II) and zinc(II) complexes were synthesized by the reaction of copper and zinc salts with 3,4‐dichlorophenylactic acid, 2‐bromophenylactic acid, biphenylacetic acid (O‐donor ligand) and bipyridine (N‐donor ligands) having the general formulae [(L)2Cu(bp)(H2O)] (1), [(BpA)2Cu(bp)] (2), [(L)2Zn(bp)(H2O)] (3) and [(L*)2Zn(bp)] (4) (L = 3,4‐dichlorophenylacetate, L* = 2‐bromophenylacetate bp = bipyridine, and BpA = biphenylacetate). Structures of all compounds were characterized through FT‐IR spectroscopy and X‐ray diffraction analysis. FT‐IR spectra of all complexes confirmed the binding mode of Cu‐O and Zn‐O. XRD data revealed that complexes 1–3 exhibited distorted octahedral arrangement, whereas complex 4 has a distorted tetrahedral environment. Micellization behavior was examined with anionic surfactant (SDS) by conductance measurement as well as absorption spectral analysis. DNA binding study was assessed through viscosity measurement and UV/Vis spectrophotometry. DPPH free radical scavenging assay was measured by UV/Vis spectrophotometry. The results showed nice biological potential of all the complexes.

Exploiting Interfacial ZnO-Cu Nanocomposites in Metal–Organic Framework Derived Catalysts: Enhancement of Catalytic Activity for CO2 Hydrogenation

“…As a result, the changed peaks for the crystal planes of (200), (020), and (011) indicate the Zn 2+ sites might be replaced by Cu ions, leading to a different coordinated environment of the crystal. Furthermore, according to previous research, 30,31 and 6) under the N 2 atmosphere at 700 °C leads to the successful synthesis of the ZnO-Cu-X-700 catalyst. The results of XRD patterns (Figure 3) indicate the peaks around 43.316°, 50.448°, and 74.124°correspond to the (111), (200), and (220) planes for cubic copper, respectively.…”

Sonochemical Synthesis, Crystal Structure and Antimicrobial Property of One‐dimensional Dinuclear Coordination Polymer

“…In the case of compound 1 strong band centered at 3398 cm –1 corresponds to asymmetric and symmetric O–H stretching vibrations modes of water molecules. [ 36 ] The strong bands at 1625 and 1670 cm –1 are attributed to asymmetric (COO – ) stretching and the strong band at 1344 cm –1 is attributed to symmetric stretching of carboxylate groups. [ 37–38 ] The absence of a strong absorption band for the stretching vibrations of the C=O bonds in the 1700–1730 cm –1 region represents the complete deprotonation of carboxylic acid groups of pdc 2– ligand.…”

Facial Synthesis, Stability, and Interaction of Ti3C2Tx@PC Composites for High-Performance Biocathode Microbial Electrosynthesis Systems

“…Renewable energy-based alternative policies must be implemented due to exhaustive consumption of fossil fuels and high energy demand. − The modernism of well-organized technology for turning greenhouse gases like carbon dioxide (CO 2 ) into highly valued products will profoundly influence the environment and the economy. − Furthermore, carbon capture and utilization technologies are becoming more popular as the decarbonization of industries and circular economy become global concerns. − The bioelectrochemical process of microbial electrosynthesis (MES) can potentially convert CO 2 into a variety of short-chain carboxylic acids, alcohols, and methane, most of which are currently created from fossil-based precursors. − It is imperative to build inexpensive modified electrode materials because they are critical for selective microbial richness and serve as sites for microbial attachment and growth. − …”
