The synthesis and characterization of new Pd(II) thiourea complexes are described. The effective catalytic performance was evaluated in the synthesis of biaryls/aryl ketones from the coupling of aryl halides/aryl esters with arylboronic acid using the Suzuki–Miyaura reaction under green conditions with low catalyst loadings.

We present novel inorganic–organic hybrid catalyst to accomplish domino multi-component reaction (MCR) for synthesis of 3-amino-2′-oxospiro[benzo[c]pyrano[3,2-a]phenazine-1,3′-indoline]-2-carbonitrile/carboxylate derivatives. This methodology offers remarkable development by easy production of H₃PMo₁₂O₄₀/Hyd-SBA-15 in regard to solving the problem of using harsh catalysts, also it demonstrates to be impressive and environmentally friendly in term of low reaction times and high yields.

1. Syntheses, structure, and spectroscopic studies of a new dinuclear Co(III) coordination compound were performed.
2. Electrocatalysis of oxygen reduction at the liquid–liquid interface and hydrogen peroxide generation by the coordination compound alone were achieved.
3. Electrocatalytic reduction of oxygen to water at the liquid–liquid interface in the presence of both the coordination compound and ferrocene was performed.

The Pd/ZrO₂@CN derived from Pd@NH₂-UiO-66(Zr) as a robust catalyst delivered remarkable stability and activity to the catalytic hydrogenation of 2,3,5-trimethylbenzoquinone (TMBQ) to 2,3,5-trimethylhydroquinone (TMHQ), a key reaction involved in vitamin E production.

A self-assembly approach was applied to construct six (4,4) mono- and double-layers, and three 5,5-c and 4,4-c binodal topological Zn (II)-based polymers with different blue luminescent emission.

(Ce^III-Mo^VI)O_x/aniline, as a novel hybrid with rod-like structure was synthesized through a wet chemical method and their catalytic activities were tested in the selective oxidation of sulfides using hydrogen peroxide as a green oxidant.

Effects of ligand denticity (bidentate and tridentate) and type of N donors (triazole and pyridine) of triazole-based ligands functionalized silica supports on properties of the resulting Pd NPs including their catalytic activities toward aerobic alcohol oxidation were investigated and compared.

This paper reports the preparation and characterization of some diorganotin (IV) adducts containing a series of pyridyl ligands. The products have been characterized using elemental analysis, IR, NMR (¹H, ¹³C, ¹¹⁹Sn, DEPT-135°) spectroscopy and X-ray crystallography. Interconnections in the four crystal structures were analyzed using Hirshfeld surface analysis. The 2D-fingerprint plots revealed that the H…H and H … C/C … H contacts are more frequent in the crystal structures.

Three multinuclear Cu (II), Zn (II) and Cd (II) complexes, [Cu₂(L)(OAc)]·CHCl₂ (1), [Zn₂(L)(OAc)(H₂O)]·3CHCl₃ (2) and [{Cd₂(L)(OAc)(CH₃CH₂OH)}₂]·2CH₃CH₂OH (3) with a single-armed salamo-like dioxime ligand H₃L have been synthesized, and characterized by FT-IR, UV–vis, X-ray crystallography and Hirshfeld surfaces analyses. Fluorescence properties of the ligand and its complexes 1–3 have also been discussed.

A new nanohybrid film (TBA)PWFe/PVA/CTS was synthesized successfully, as a highly active catalyst. The catalytic activity of (TBA)PWFe/PVA/CTS was evaluated in the CODS of real gas oil. Also,the solutions of heterocyclic thiophenic compounds (HTCs) in n-heptanewere tasted as simulated fuels. It was found that the removal efficiency of HTCs in the presence of (TBA)PWFe/PVA/CTS catalyst reached as high as 95% at 60 °C after 2 h.

A novel luminescent metal–organic framework with pillared structure has been constructed using 2,3,5,6-tetrakis(4-carboxyphenyl)pyrazine (H₄TCPP) and 4,4′-bipyridyl ligands. It exhibits excellent physical and chemical stability, and luminescent sensing ability for 2,4,6-trinitrophenol and Fe³⁺ ions.
