Synthesis, Structural, and Antimicrobial Studies of Some New Coordination Compounds of Palladium(II) with Azomethines Derived from Amino Acids

Abstract

Some new coordination compounds of palladium(II) have been synthesized by the reaction of palladium(II) acetate with azomethines in a 1 : 2 molar ratio using acetonitrile as a reaction medium. Azomethines used in these studies have been prepared by the condensation of 2-acetyl �uorene and 4-acetyl biphenyl with glycine, alanine, valine, and leucine in methanol. An attempt has been made to probe their bonding and structures on the basis of elemental analyses and IR, 1 H, and 13 C NMR spectral studies. Pd(II) compounds have been found to be more active than their uncomplexed ligands as both of them were screened for antibacterial, antifungal, and insecticidal activities.

Crystal structure of bis(2-{1-[(E)-(4-fluorobenzyl)imino]ethyl}phenolato-κ2N,O)palladium(II)

“…assignable to the aromatic protons. A corresponding multiplet appears in almost the same position in the spectrum of the Pd II complex (compound 1) as that observed by Gupta et al (2013). Singlets for aliphatic methylene (-CH 2 ) and methyl (-CH 3 ) protons appear at 5.11 and 2.32 p.p.m., respectively.…”

Preparation, spectroscopic analysis, and biological assessment of heteroleptic Zr(II) and Pd(II) complexes from Otc/Sal mixed ligands

“…The C-H stretching and bending vibration lies in the region of 3061 cm -1 and 2941 cm -1 respectively [30,31]. Similarly, the strong absorption bands with stretching vibration of the carbonyl (C=O) groupwere seen at 1614 cm -1 and 1622 cm -1 regions in the spectrum [32,33]. The aromatic υ(C=C) absorption bands are at 1502 cm -1 and 1455 cm -1 respectively [34].…”

Design, preparation and characterization of magnetic nanoparticles functionalized with chitosan/Schiff base and their use as a reusable nanocatalyst for the green synthesis of 1H-isochromenes under mild conditions

“… 4 These compounds are very important and widely used because of their interesting physical and chemical properties. 5 A range of biological effects have also been reported for Schiff bases, including antifungal, antipyretic, 6 antibacterial, 7 antimalarial, and antiproliferative 8 effects. These compounds are excitingly used as pigments and dyes, catalysts, and polymer stabilizers.…”
