“…The structural parameters of main interest, such as bond lengths and angles surrounding the metal center, are listed in Table S1, following the atom numbering defined therein. An inspection of the computed parameters reveals that the Pd-N and Pd-Cl bond lengths are within the regular range reported in the literature [31], and the Pd metal center adopts a quite regular square planar conformation, with angles ranging between 90° and 95° between Pd and the chloride ions, and slightly smaller between Pd and the nitrogens of the bidentate ligands (81°-83°) (See Table S1).…”

Three new palladium complexes ([Pd(DABA)Cl2], [Pd(CPDA)Cl2], and [Pd(HZPY)Cl2]) bearing dinitrogen ligands (DABA: 3,4-diaminobenzoic acid; CPDA: 4-chloro–o-phenylenediamine; HZPY: 2-hydraziniopyridine) were synthesized, characterized, and tested against breast cancer (MCF-7), prostate carcinoma cell line (PC3) and liver carcinoma cell line (HEPG2). [Pd(DABA)Cl2] complex exhibited the highest inhibition percentage, lying between 68–71%. The hydrolysis mechanism of each palladium complex, the key step preceding the binding to the biological target, as well as their photophysical properties were explored by means of DFT and TDDFT computations. Results indicate a faster hydrolysis process for the Pd(DABA)Cl2 complex. The computed activation energies for the first and second hydrolysis processes suggest that all the compounds could reach DNA in their monohydrated form.

“…Figure shows the FT-IR and Raman spectra that were used to determine their structural properties. From the FT-IR spectrum, it is possible to observe the characteristic bands of the bidentate ligand of the Pd-complex, referring to the triazine and pyridine groups, and showing good agreement with the literature. − Symmetrical and asymmetrical stretches of the amine group linked to the aromatic ring triazines are confirmed in regions of 3069 and 3193 cm –1 , respectively. The coordination of the N atom to the metallic center of Pd, on the other hand, can be characterized by the stretch ν(Pd–N) in 587 cm –1 , while the Pd–Cl bond is found in the low-frequency regions of the spectrum.…”

Methane is an abundant resource and the main constituent of natural gas. It can be converted into higher value-added products and as a subproduct of electricity co-generation. The application of polymer electrolyte reactors for the partial oxidation of methane to methanol to co-generate power and chemical products is a topic of great interest for gas and petroleum industries, especially with the use of materials with a lower amount of metals, such as palladium complex. In this study, we investigate the ideal relationship between cis -[6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine(dichloride)palladium(II)] (Pd-complex) nanostructure and carbon to obtain a stable, conductive, and functional reagent diffusion electrode. The physical and structural properties of the material were analyzed by Fourier transform infrared (FT-IR) and Raman spectroscopies, transmission electron microscopy (TEM), and X-ray powder diffraction (XRD) techniques. The electrocatalytic activity studies revealed that the most active proportion was 20% of Pd-complex supported on carbon (m/m), which was measured with lower values of open-circuit and power density but with higher efficiency in methanol production with reaction rates of r = 4.2 mol L –1 ·h –1 at 0.05 V.

“…The schematic preparation of ligands and complexes (complex structures are proposed structures) consistent with the results we obtained with spectroscopic and computational methods in our previous study. [38] Thermal analysis (TG/DTA/DTG) of complexes was performed under N 2 atmosphere in the temperature range from ambient to 900 C. The TG/DTA/DTG curve of PyrBt-Pd complex is shown in Figure S7. The thermal dehydration takes place between 30 C and 192 C, with a mass loss 4.77% (calcd.…”

The use of continuous flow systems in chemical synthesis provides great advantages in terms of sustainability, efficiency, and safety. The ability to control reaction parameters such as temperature, pressure, and catalyst exposure in flow system enables rapid optimization of reaction conditions. In the present study, palladium complexes of 1‐(piridin‐2‐il)‐1H‐benzo[d][1,2,3]triazol, N‐((1H‐benzo[d][1,2,3]triazol‐1‐il)metil)piridin‐2‐amin, and (1H‐benzo[d][1,2,3]triazol‐1‐yl)(pyridin‐2‐yl)methanone ligands were synthesized and characterized. The catalytic activities of complexes are investigated in the hydrogenation of various alkenes such as styrene, cyclohexene, and 1‐octene under continuous flow conditions. The complexes showed very high activity at 10‐bar H2 pressure and 50°C for short periods of 5–10 min. The catalysts reused for 10 cycles with no significant loss of catalytic activity.
