The mol-ecular structures of the chiral title compounds, [Pd(C19H28N2)2I2], (I), and [Pd(C19H28N2)Cl2(C18H15P)], (II), show a distorted square-planar coordination around the Pd(II) atoms with two halogenide (Hal) ligands each and two N-heterocyclic carbene (NHC) ligands in (I) or one NHC and one tri-phenyl-phosphane ligand in (II). The deviations of the Pd(II) atoms from the L 2Hal2 best plane (L = NHC or tri-phenyl-phosphane ligand) are 0.206 (1) Å for (I) and 0.052 (1) Å for (II). The crystal packings exhibit inter-molecular C-H⋯Hal hydrogen bonds.

Buchwald-Hartwig (BH) aminations are crucial for synthesizing arylamine motifs in numerous bioactive molecules and fine chemicals. While homogeneous palladium complexes can be effective catalysts, their high costs and environmental impact motivate the search for alternative approaches. Heterogeneous palladium single-atom catalysts (SAC) offer promising recoverable alternatives in C-C cross-couplings.

The reuse of agricultural waste brings significant benefits but still faces a multitude of challenges. In this work, novel precious metal sorbents were constructed by grafting 1,3,4-thiadiazole-2-thiol (MTD) and 2,5-dithiadiazole-1,3,4-thiadiazole (DMTD) onto native corncob, which could rapidly and selectively recover palladium (Pd) from metallurgical wastewater. The characterization of the sorbents by powder X-ray diffraction indicated that introducing MTD or DMTD on native corncob did not alter the crystallinity and inherent structural framework.

Two new complexes of Pd(II), [Pd(L1)Cl]Cl (Pd1) and [Pd(L2)Cl]Cl (Pd2), (where L1 = ,-bis(5-methylthiazol-2-yl)pyridine-2,6-dicarboxamide and L2 = ,-di(benzo[]thiazol-2-yl)pyridine-2.6-dicarboxamide) were synthesized. Characterization of the complexes was performed using elemental analysis, IR, H NMR spectroscopy and MALDI-TOF mass spectrometry.

Article Synopsis
- The study introduces metalated graphynes (MGYs), which incorporate transition-metal single atoms into graphdiyne frameworks for creating advanced catalysts.
- Four photocatalysts using NiII, PdII, PtII, and HgII were synthesized, with NiII showing the best performance in CO generation.
- The exceptional efficiency of the TEPY-Ni-GY catalyst is due to its unique structural features that enhance electron transfer and improve CO2 adsorption, making it a viable option for CO2 reduction.
