“…The maximum absorption (λ max ) of the [Pd(SCN) 4 ] 2– complex should be observed at around 315 nm; however, it was hardly observed owing to overlap with the broad absorption of the PIM components. Nevertheless, the [Pd(SCN) 4 ] 2– complex absorption shoulder at around 450–500 nm was clearly observed owing to its intense orange color. , In the receiving solution following Pd(II) transport, a broad UV–vis spectrum from 200 to 500 nm was observed (Figure c). For easier interpretation, the spectrum was deconvolved using a Gaussian function, resulting in four fit peaks.…”

Mutual separation of platinum group metals (PGMs) is a particularly challenging issue in metal recovery technology. In this study, we report the successful separation of Pt(IV), Pd(II), and Rh(III) by sequential transport through polymer inclusion membranes (PIMs) containing the ionic liquid trioctyl(dodecyl) phosphonium chloride (P 88812 Cl) as a metal carrier. This study describes the screening of suitable receiving solutions, optimization of the operating conditions, establishing a possible transport mechanism, and evaluation of the membrane stability. In the first transport sequence, Pt(IV) was selectively transported into the receiving solution with a recovery of >95%, while Pd(II) and Rh(III) remained in the feed solution. In the second transport sequence, high-purity Pd(II) was transported into the receiving solution with a recovery of >95%, while Rh(III) remained completely in the feed solution. Furthermore, the PIM exhibited a stable performance with multiple uses over a 4-week period during which four Pt(IV) and Pd(II) sequential transport cycles were continuously carried out.

Promising Antimicrobial Activity of an Oxime Based Palladium(II) Complex

et al. 2017

This work delineates with the development of a novel oxime based palladium complex as a promising antimicrobial agent. A novel oxime based ligand, 3-[(2-hydroxy-naphthalen-1-ylmethylene)-hydrazono]-butan-2-one oxime (LH), has been employed to synthesize an orange, monomeric, diamagnetic palladium(II) compound, [Pd(L)(Cl)] (1) in moderate yield. LH is a monocondensate Schiff-base of 2,3-butanedionemonoxime monohydrazone and 2-hydroxy-1-naphthaldehyde in tetrahydrofuran. Both the ligand and its palladium compound have been characterized by spectroscopic and analytical techniques. The X-ray crystal structure of 1 reveals that the palladium center in [Pd(L)(Cl)] is nested in a distorted square-planar 'N 2 OCl' coordination environment. The electrochemical behavior of [Pd (L)(Cl)] in DMF shows a Pd(II)/ Pd(I) irreversible reduction couple. The in vitro antibacterial activity of [Pd(L)(Cl)] was tested against a good number of human pathogenic Grampositive and Gram-negative bacterial cell lines. The in vitro antifungal activity of the titled palladium compound was screened against several pathogenic fungal strains. The promising antimicrobial efficacy of the palladium compound was corroborated through SEM study.

− ligand is replaced by two monodentate ligands that occupy axial positions. All compounds were characterized on the basis of analytical, spectroscopic, conductometric and magnetochemical data. The crystal structure of cis-CdL C (NO 3 )](NO 3 ) was determined by X-ray crystallography and showed the cadmium centre to exist within a cis-N 4 O 2 donor set that defined a distorted octahedral geometry. Non-systematic variations in the Cd-O and Cd-N bond distances were correlated with significant hydrogen bonding interactions operating in the crystal structure. The latter interactions led to the formation of supramolecular two-dimensional arrays. The anti-fungal and anti-bacterial activities of these compounds were studied against some phytopathogenic fungi and bacteria. Coordination of L C by cadmium resulted in more effective anti-microbial agents; no significant dependence upon the nature of the counter-ion was detected. Copyright
