“…The structures of palladium complexes were optimized using DFT with the B3LYP hybrid functional, by using a basis set of LanL2DZ, which is very common in palladium complexes calculations. Computations have been performed using the Gaussian 16 program package [ 29 , 30 , 31 , 32 , 33 ].…”

Tropaeolin OO as a Chemical Sensor for a Trace Amount of Pd(II) Ions Determination

The selective determination of metals in waste solutions is a very important aspect of the industry and environmental protection. Knowledge of the contents and composition of the waste can contribute to design an efficient process separation and recovery of valuable metals. The problematic issue is primarily the correct determination of metals with similar properties such as palladium and platinum. Thus this paper focuses on the development of a selective method that enables Pd(II) determination in the presence of Pt(IV) ions using the azo-dye tropaeolin OO (TR). For this purpose, the process of the metalorganic complex formation and Pd(II) ions determination were studied by using UV–Vis spectrophotometry under different conditions: solvents (water and B-R buffer), pH (2.09–6.09), temperature (20–60 °C), anions and cations concentrations. The formed metalorganic complex between Pd and tropaeolin OO allows for distinguishing Pd(II) ions from both platinum complexes, i.e. Pt(II), Pt(IV). Moreover, the proposed method can be applied to solutions containing both chloride and chlorate ions. The obtained characteristic spectrum with two maxima allows the determination of palladium even in the presence of other cations (Na, K, Mg, Zn, Co, Ni, Al) and changed concentrations of Pt(IV) ions. Furthermore, the developed spectrophotometric method for the Pd(II) ions determination using tropaeolin OO is characterized by high selectivity towards palladium ions.

“…Signals in the 600–400 cm −1 range are characteristic of the vibrations of the metal‐donor group bond and they attest the presence of Pd in the newly synthesized compounds. The values are characteristic of the Pd−O [19] and Pd‐(C=C) bonds, the Pd−Cl bond having lower values [20] …”

“…The values are characteristic of the PdÀ O [19] and Pd-(C=C) bonds, the PdÀ Cl bond having lower values. [20] Changes in the spectra were noticed in the sp 2 CÀ H, sp 3 CÀ H and C=C stretch domains and in the CÀ O and OH region (see Table 4). The spectral data indicated the coordination of palladium with one double bond and one O atom for complexes [PdCl 2 L1] and [PdCl 2 L2].…”

Palladium (II) complexes of three polydentate non‐planar bicyclo[4.4.0]decane ligands with at least one double bond and bridgehead cis‐substituents CH2OH or CH2OCH2 were prepared in order to investigate the role of stereochemistry and donor nucleophilicity in the Pd coordination. All ligands and their corresponding complexes were characterized using NMR, solid‐state NMR (ssNMR), HR‐MS, ATR‐IR, DSC‐TGA. For ligand cis‐1,4,5,8‐tetrahydro‐naphthalene‐4a,8a‐diyl‐dimethanol (L2) the X‐ray structure corresponded to the DFT optimised structure. The HR‐MS and thermal analysis data confirmed a complexation ratio: ligand/PdCl2 of 1/1. The experimental data as well as the computations are consistent with the structures proposed based on 13C‐ssNMR, namely palladium coordinates with one double bond and an oxygen atom for ligands with CH2OH groups and with both double bonds for the ligand with an etheric bridge, showing the prevalence of stereochemistry over donor nucleophilicity for such non‐planar ligands.
