A series of gas-phase reactants is used to treat a Cu-exchanged mordenite zeolite with the aim studying influence reaction environment on formation Cu pairs. The rearrangement ions form multimeric sites as function their oxidation state was probed by X-ray absorption spectroscopy (XAS) and also applying advanced analysis through wavelet transform, method able specifically locate Cu–Cu interacti...

Using N2O4 donor symmetric ligand H2L and dca co-ligand, two new isostructural dinuclear CuII–LnIII complexes [Cu(Cl)(L)Ln(NO3)(CH3OH)(H2O)(dca)] [Ln=Ho (1CuHo), Gd (2CuGd)] [H2L = 6,6′-((1E,1′E)-(ethane-1,2-diylbis(azaneylylidene))bis(methaneylylidene))bis(2-methoxyphenol); dca=dicyanamide] were designed, synthesized studied. In the compounds, geometric environment around nine-coordinated Ln(I...
